1-[4-(PYRIDIN-2-YL)PHENYL]-5(S)-2,5-BIS [(TERT-BUTYLOXYCARBONYL) AMINO]-4(S)-HYDROXYL-6-PHENYL-2-AZAHEXANE(CAS: 198904-86-8)

Atazanavir EP Impurity J is a semi-crystalline compound with a molecular weight of approximately 578.8 g/mol. It has a melting point around 135°C and low solubility in water but is soluble in common organic solvents like DMF and DMSO. This impurity is reactive towards bases and can undergo nucleophilic substitution reactions.

Atazanavir EP Impurity J is synthesized through a multi-step process starting from t-butyl ethers, involving acid-catalyzed rearrangement and amidation reactions. The synthesis yields moderate to high purity products with excellent selectivity. Common catalysts include sulfuric acid, and the overall yield can reach up to 85%.

Atazanavir EP Impurity J is primarily used in the pharmaceutical industry as an intermediate in the synthesis of antiviral drugs. It is also relevant in research for studying the structural and functional properties of atazanavir analogs. Limited applications in polymer science and material science are also explored.

When handling Atazanavir EP Impurity J, it is essential to use personal protective equipment (PPE) such as gloves, goggles, and lab coats. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbents and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.
