About Budesonide WS

Budesonide WS is a high-purity reference standard of Budesonide carrying the CAS registry number 51333-22-3. Formula C25H34O6, molecular weight 430.5 g/mol. Alternative names: Budesonide and Bidien.

The product is provided as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Budesonide standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide. Stock is available for quick dispatch.
