Atazanavir Impurity 20(CAS: 102123-74-0)

Atazanavir Impurity 20 (CAS: 102123-74-0) is a crystalline compound with a molecular weight of approximately 652.72 g/mol. It is poorly water-soluble, with a solubility of about 1 mg/L. This impurity is relatively stable under normal conditions but may react with strong acids or bases. It is important to handle it under appropriate storage conditions to maintain its stability.

Atazanavir Impurity 20 (CAS: 102123-74-0) is typically synthesized using a multistep process involving the condensation of aromatic amines and aldehydes, followed by cyclization and subsequent transformation. This synthesis often requires the use of catalysts such as palladium and requires precise control over reaction conditions to achieve high yields and selectivity.

Atazanavir Impurity 20 (CAS: 102123-74-0) is primarily used in the pharmaceutical industry as an impurity in the synthesis and production of Atazanavir, a widely used antiretroviral drug. While it has limited direct applications, it plays a crucial role in ensuring the purity of Atazanavir products, making it essential for the pharmaceutical sector.

When handling Atazanavir Impurity 20 (CAS: 102123-74-0), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area, preferably in a fume hood, to minimize inhalation risks. In case of spillage, the area should be thoroughly cleaned with appropriate solvents, and the spill documentation should be recorded following safety protocols. Always refer to the Safety Data Sheet (SDS) for detailed instructions.
