At Maison Chemical, we recommend confirming the intended use, required assay, impurity limits, and documentation before comparing quotations. The compound has a molecular formula of C₆H₈O₂ and a molecular weight of 112.13 g/mol. These identity details are a starting point for procurement, not a substitute for checking the current batch’s certificate of analysis (COA) and safety documentation.

Key Takeaways

• Use CAS 637-88-7 and the chemical name together to identify the requested material.
• Match assay, impurity limits, and analytical methods to your synthesis and quality requirements.
• Ask for current batch documentation, packaging information, and a confirmed delivery estimate before placing an order.
• Consider any sample size or assay threshold as a project-specific request, not as a guaranteed standard product specification.

Who This Guide Is For

This guide is intended for procurement teams, process chemists, research and development groups, and manufacturers evaluating 1,4-Cyclohexanedione as a synthesis input. It is especially useful when you need to compare supplier offers that may differ in assay, impurity reporting, packaging, or documentation. If you are selecting the material for a regulated or tightly controlled process, involve your quality and safety teams before approving a source.

Product Overview and Chemical Context

Identity and Basic Properties

1,4-Cyclohexanedione is a six-membered cyclic compound containing ketone groups at positions 1 and 4. Its CAS Registry Number is 637-88-7, and its molecular formula is C₆H₈O₂. A commonly cited melting-point range is approximately 78–82 °C; because values and test conditions can vary between references and batches, we recommend confirming the relevant specification with the supplier and batch documentation.

Do not use a general property listing as a substitute for a lot-specific COA. For purchasing, the most useful information is the identity confirmation, assay result, impurity profile where available, appearance description, test method, and any agreed acceptance criteria. If a property is important to your process, specify how it should be measured and documented before ordering.

Grades, Specifications, and Documentation

Buyers may encounter offers described by assay level, intended use, or supplier-specific grade terminology. Such labels are not automatically equivalent across suppliers, so compare the actual specification and analytical methods rather than relying on grade names alone. A proposed assay threshold such as 98.0% can be used as an example starting point for a request for quotation, but it is not a claim about every available batch or a universal requirement.

For a meaningful comparison, request a current COA and confirm which test method supports each reported value. Where your process is sensitive to particular by-products or residual materials, identify those limits explicitly instead of assuming they are covered by a general assay result. Also confirm whether the supplier can provide an SDS and any additional documents required by your organization.

Potential Uses and Application Matching

Buyers generally evaluate 1,4-Cyclohexanedione as a chemical intermediate for synthesis rather than as a finished-use ingredient. Its diketone structure can support further chemical transformations, making it relevant to research and development and to the manufacture of selected fine-chemical intermediates. The suitability of a given batch depends on the chemistry being performed and the impurity profile your route can tolerate.

For early-stage research, a smaller evaluation quantity may help a team check material identity and performance in its own procedure. For example, you could request 25 g as an illustrative sample quantity if that is sufficient for your screening plan; this is a planning example, not a standard pack size or a promise of availability. For established production, assess the required quantity, repeat-order needs, and incoming quality checks together.

A Practical Selection Framework

1. Define the Application and Acceptance Criteria

Start by describing the intended synthesis stage and the consequences of variation in the starting material. Decide whether you need a minimum assay, limits for named impurities, a particular appearance, or additional identification tests. If you do not yet know which limits matter, consult your process chemist and quality team before fixing the purchase specification.

2. Compare Offers on an Equivalent Basis

Ask each supplier to quote against the same quantity, specification, packaging expectations, and requested documents. Check whether the price applies to the stated grade and whether freight, export packing, or other charges are included. A lower quoted price is difficult to evaluate if the assay basis, delivery terms, or documentation differ.

3. Confirm Quantity, Packaging, and Timing

Share both your immediate requirement and an estimate of likely repeat demand, while making clear which quantities are firm. A 1 kg quantity can serve as an illustrative commercial inquiry unit, but it is not a standard minimum order quantity or a representation of current stock. Ask the supplier to confirm available pack sizes, any special handling or packaging requirements, and a delivery estimate for the specific order.

4. Review the Supplier’s Documentation and Communication

Request the COA for the offered batch when available and check that the product name, CAS number, lot identification, test results, and specification are consistent. Review the SDS for relevant hazards, storage guidance, and handling precautions before receiving or using the material. Clear answers about specifications and logistics are useful indicators of whether a supplier can support your purchasing workflow; they are not a substitute for your own supplier qualification process.

Pricing, MOQ, and Lead-Time Considerations

The price of 1,4-Cyclohexanedione can depend on requested quantity, specification, packaging, destination, and order timing. Minimum order quantities and lead times are supplier- and order-specific, so we avoid treating any single figure as universal. Ask for a quotation that states the quoted quantity, specification, validity period, delivery basis, and any additional charges.

When comparing suppliers, consider the total cost of obtaining an acceptable, documented batch rather than the unit price alone. A different pack size, extra testing request, or export requirement may affect the final quotation and schedule. For planned production, share your target delivery window early and ask whether future supply can be discussed separately from the current order commitment.

Common Buyer Mistakes to Avoid

• Using the name alone: Include CAS 637-88-7 in your inquiry to reduce the risk of product identification errors.
• Assuming assay tells the whole story: Ask about the analytical method and any process-critical impurities.
• Comparing non-equivalent quotations: Align quantity, specification, packaging, and delivery terms before judging price.
• Leaving document needs until after ordering: Confirm COA, SDS, and any internal documentation requirements in advance.
• Assuming stock or lead time: Request current confirmation for the quantity and destination you need.

How Maison Chemical Can Support Your Inquiry

At Maison Chemical, we can review your requested quantity, specification, application context, and destination so that an inquiry can be assessed against the details that matter to your purchase. We encourage buyers to send any required assay threshold, impurity limits, packaging preferences, and document requests with the initial request for quotation. This helps us clarify what can be offered and identify any points that need confirmation before an order is placed.

When you contact us, include the product name, CAS 637-88-7, target quantity, destination, and desired delivery window. If you have an internal specification or a preferred analytical method, share it for review rather than relying on a general grade description. We can then respond with product and commercial information for your evaluation, subject to confirmation for the specific order.
