About Atropic Acid

Atropic Acid (CAS 492-38-6) is an impurity of Ipratropium offered by Vaqora Chemicals. Formula C9H8O2, molecular weight 148.16 g/mol. The IUPAC name is 2-phenylprop-2-enoic acid. Alternative names: Acrylic acid, 2-phenyl- and 2-Propenoic acid, 2-phenyl-.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

As a characterised impurity of Ipratropium, 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.

We offer Atropic Acid in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
