In the realm of pharmaceutical manufacturing, the precise control of chemical processes is paramount. Every step, from raw material sourcing to final product formulation, is subject to stringent quality checks. Central to these checks is the accurate identification and management of impurities. Azacitidine Impurity 1, bearing the CAS number 157771-77-2, serves as a crucial pharmaceutical intermediate and reference standard, playing an integral role in ensuring the quality and safety of Azacitidine-based medications. Understanding its importance is key for R&D scientists, procurement managers, and quality control specialists.

As a pharmaceutical intermediate, Azacitidine Impurity 1 is not a component of the final drug product itself, but rather a substance used during its synthesis or analysis. Its primary function is as a reference standard, enabling the development and validation of analytical methods that detect and quantify specific impurities within Azacitidine. This process is critical for regulatory compliance and for ensuring that the API meets established purity profiles. The availability of a well-characterized impurity standard like Azacitidine Impurity 1 (CAS 157771-77-2) from a reliable manufacturer is therefore indispensable for pharmaceutical companies.

The market for such specialized chemicals is global, with many reputable manufacturers and suppliers located in China. These suppliers often possess the advanced synthesis capabilities and quality control infrastructure necessary to produce high-purity intermediates. When a pharmaceutical company decides to buy Azacitidine Impurity 1, they are not just purchasing a chemical; they are investing in the reliability of their analytical data and, ultimately, the safety of their patients. Working with suppliers who can provide consistent quality and timely delivery is a significant advantage.

The systematic name for Azacitidine Impurity 1 is 4-amino-1-((2S,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1,3,5-triazin-2(1H)-one. This chemical identity, coupled with its CAS number, allows for precise communication and procurement across the industry. Pharmaceutical R&D teams utilize this impurity to refine their analytical techniques, ensuring that any deviations in the manufacturing process are promptly identified and addressed. For manufacturers, the ability to consistently supply this compound underscores their commitment to supporting the pharmaceutical industry's critical quality needs.

In conclusion, Azacitidine Impurity 1 (CAS 157771-77-2) is a vital pharmaceutical intermediate that underpins the quality control of Azacitidine. Its role as a reference standard makes it an essential tool for analytical chemists and researchers. Sourcing this compound from dedicated manufacturers and suppliers, particularly those in China known for their quality and capacity, is crucial for any pharmaceutical organization aiming to maintain the highest standards of drug purity and safety.
