Erdosteine

About Erdosteine

Erdosteine is a high-purity reference standard of Erdosteine carrying the CAS registry number 84611-23-4. With the molecular formula C8H11NO4S2, it has a molar mass of 249.3 g/mol. Systematically, it is named 2-[2-oxo-2-[(2-oxothiolan-3-yl)amino]ethyl]sulfanylacetic acid. Alternative names: RV-144 and Erdotin.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Erdosteine standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Our customers for this product work in 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.
