Patulin

About Patulin

Patulin is a high-purity reference standard of Aflatoxin carrying the CAS registry number 149-29-1. With the molecular formula C7H6O4, it has a molar mass of 154.12 g/mol. The IUPAC name is 4-hydroxy-4,6-dihydrofuro[3,2-c]pyran-2-one. Common synonyms include Clavacin and Clavatin.

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. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

Laboratories use this Aflatoxin 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.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Patulin is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
