For professionals in the chemical and pharmaceutical industries, the precise identification and understanding of a chemical intermediate's specifications are non-negotiable. When looking to buy 4,6-Pyrimidinedicarboxylic Acid (CAS 16490-02-1), procurement managers and R&D scientists must pay close attention to several key attributes to ensure it meets their application requirements. This guide outlines these critical specifications and what to look for when sourcing from China manufacturers.

The most fundamental identifier is the CAS Number: 16490-02-1. This unique numerical identifier is essential for precise product identification and avoids confusion with other isomers or related compounds. When you search for '4,6-pyrimidinedicarboxylic acid', always verify that the CAS number matches your needs.

Purity is paramount, especially for applications in pharmaceutical synthesis and fine chemicals. We offer this compound with a minimum purity of 97%. For a chemical intermediate, this level of purity ensures that reactions proceed as expected and that downstream products are not contaminated. Always inquire about the purity level when obtaining a 'chemical intermediate price' or quote.

The Molecular Formula (C6H4N2O4) and Molecular Weight (168.107) are crucial for stoichiometric calculations in synthesis. Understanding these parameters ensures accurate dosing and reaction planning. Manufacturers should readily provide this information.

Physical properties such as Appearance (e.g., White crystalline powder) and Melting Point (N/A in source data, but typical for solid organic acids) give an initial indication of the compound's state and can sometimes hint at its purity or polymorphic form. Boiling Point (497.4±30.0 °C at 760 mmHg) and Density (1.7±0.1 g/cm³) are also important for process design, especially if distillation or specific handling procedures are involved.

Packaging options are also a practical consideration. Availability in various sizes, such as 25g, 100g, 500g, and bulk, caters to different scales of operation, from laboratory research to industrial production. When you plan to 'buy 4,6-pyrimidinedicarboxylic acid', consider the packaging that best suits your storage and usage patterns.

As a leading '4,6-pyrimidinedicarboxylic acid manufacturer in China', we emphasize transparency in providing these specifications. We encourage you to request a detailed Certificate of Analysis with your order and to reach out for a quote or sample to verify these critical parameters for yourself.
