About Alternariol

Alternariol is a high-purity reference standard of Alternariol carrying the CAS registry number 641-38-3. With the molecular formula C14H10O5, it has a molar mass of 258.23 g/mol. Systematically, it is named 3,7,9-trihydroxy-1-methylbenzo[c]chromen-6-one. Common synonyms include Alternariol from Alternaria sp. and 3,4',5-Trihydroxy-6'-methyldibenzo-a-pyrone.

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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Alternariol 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, Alternariol is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
