Atazanavir Impurity 21(CAS: 98737-29-2)

Atazanavir Impurity 21 (CAS: 98737-29-2) is a chemical compound identified as a byproduct or degradation product of Atazanavir, a protease inhibitor used in HIV treatment. It has the molecular formula C22H27N5O3S and is typically characterized by its structural similarity to the parent drug, with specific functional group modifications. This impurity is relevant in pharmaceutical quality control and research for drug development.

Atazanavir Impurity 21 (CAS: 98737-29-2) is primarily used in pharmaceutical research to study impurity profiles and degradation pathways of Atazanavir. It also plays a role in drug development processes for quality assurance and in analytical chemistry to ensure the purity of HIV medications. Its applications are limited to these specialized fields, as it is not used as an active ingredient.

Atazanavir Impurity 21 (CAS: 98737-29-2) is generally considered less toxic than the active drug Atazanavir but should still be handled with care. Safety protocols include using appropriate personal protective equipment (PPE) and following standard laboratory practices. Its safety classification depends on exposure levels, and it is not typically deemed hazardous under controlled conditions, though regulatory guidelines may apply.

Atazanavir Impurity 21 (CAS: 98737-29-2) should be stored in a cool, dark place at 2-8°C to maintain stability. It requires airtight, moisture-proof containers, preferably made of glass or stainless steel, to prevent degradation. Avoid exposure to light, humidity, and air to ensure long-term preservation and compliance with pharmaceutical storage standards.
