About Aziridine

Aziridine (CAS 151-56-4) is a high-purity reference standard of Aziridine offered by Vaqora Chemicals. The compound has the formula C2H5N, corresponding to a molecular weight of 43.07 g/mol. Common synonyms include Ethylenimine and Azacyclopropane.

The product is provided 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 “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Aziridine standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

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