About 5-Hydroxymaltol

Vaqora Chemicals supplies 5-Hydroxymaltol, a metabolite / degradant standard registered under CAS number 1073-96-7. Formula C6H6O4, molecular weight 142.11 g/mol. Systematically, it is named 3,5-dihydroxy-2-methylpyran-4-one. It is also known as 3,5-Dihydroxy-2-methyl-4H-pyran-4-one or 4H-Pyran-4-one, 3,5-dihydroxy-2-methyl-.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Analytical teams use this compound to identify metabolites and degradants, to validate stability-indicating methods (AMV) and to support QC and regulatory filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

We offer 5-Hydroxymaltol in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
