About Zolpidic acid

Zolpidic acid (CAS 189005-44-5) is an impurity of Zolpidem offered by Vaqora Chemicals. The compound has the formula C17H16N2O2, corresponding to a molecular weight of 280.32 g/mol. Systematically, it is named 2-[6-methyl-2-(4-methylphenyl)imidazo[1,2-a]pyridin-3-yl]acetic acid. Alternative names: Zolpidem acid.

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.

As a characterised impurity of Zolpidem, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory 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.
