The industrial application of chemical compounds demands a rigorous understanding of their specifications. For 2,4,5,6-Tetraaminopyrimidine sulfate, a compound frequently utilized as a pharmaceutical intermediate, adherence to strict quality parameters is paramount. Manufacturers and industrial chemists alike rely on precise data to ensure successful and scalable production.

The primary specification that defines the usability of 2,4,5,6-Tetraaminopyrimidine sulfate in industrial settings is its assay, which dictates the percentage of the desired compound present. An assay of ≥98.0% is a common standard, ensuring that the bulk of the material is indeed the active chemical. This is critical when this intermediate is used in the synthesis of pharmaceuticals like Methotrexate, where even minor deviations in purity can have significant consequences on the final drug product's efficacy and safety. Sourcing from a reliable manufacturer in China that can consistently meet this specification is a key consideration for industrial procurement.

Beyond the assay, impurity profiling is equally important. Specifications regarding 'single impurity' (≤1.0%) and 'total impurities' (≤2.0%) provide crucial insights into the overall quality of the product. High impurity levels can interfere with chemical reactions, lead to the formation of unwanted byproducts, and necessitate costly purification steps. For industrial users looking to buy 2,4,5,6-Tetraaminopyrimidine sulfate, understanding these limits and how they are controlled by the supplier is vital. This due diligence helps in selecting a chemical intermediate that will perform reliably in large-scale manufacturing processes.

Furthermore, the physical characteristics, such as the appearance (yellow crystalline powder) and loss on drying (≤2.0%), also play a role in industrial handling and storage. These parameters contribute to the overall quality assurance of the chemical. As industrial demands grow, the importance of transparent and detailed specifications from chemical intermediate suppliers in China and globally cannot be overstated, ensuring that the supply chain remains robust and dependable.
