How should Betamethasone (CAS: 378-44-9) be stored?

Answer

Betamethasone (Betamethasone Acetate EP Impurity A, Betamethasone Dipropionate EP Impurity A, Betamethasone Valerate EP Impurity A, Dexamethasone EP Impurity B)
Betamethasone should be stored in a cool, dry place away from direct light. It is typically kept at a temperature between 15°C to 25°C (59°F to 77°F) and a relative humidity level below 60% to maintain stability. Proper storage in airtight containers prevents degradation and contamination. Always check the product label for specific storage requirements and follow them to ensure product integrity.
