Besifloxacin Impurity B(CAS: 101987-89-7)

Besifloxacin Impurity B (CAS: 101987-89-7) is a byproduct of the synthesis process of besifloxacin, a fluoroquinolone antibiotic used in ophthalmic treatments. It is a white to off-white solid with a molecular weight of approximately 456.6 g/mol and a melting point around 235-238°C.

Besifloxacin Impurity B (CAS: 101987-89-7) is primarily used as a quality control reference for the pharmaceutical analysis of besifloxacin. It is crucial for ensuring product purity and compliance with regulatory standards.

Besifloxacin Impurity B (CAS: 101987-89-7) is generally safe when handled properly. However, it is recommended to use appropriate personal protective equipment such as gloves and safety glasses to minimize potential skin and eye contact. Avoid inhaling dust and ensure good ventilation during handling.

Besifloxacin Impurity B (CAS: 101987-89-7) should be stored in a tightly sealed container to protect it from moisture and light. Store in a cool, dry place, ideally at room temperature (15-25°C) and away from direct sunlight. Do not expose to extreme temperatures or humidity, as this can affect its stability and purity.
