About Quercetin

Listed under CAS 117-39-5, Quercetin is a high-purity reference standard of Quercetin available from Vaqora Chemicals. Formula C15H10O7, molecular weight 302.23 g/mol. Its systematic (IUPAC) name is 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxychromen-4-one. Alternative names: Sophoretin and Meletin.

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.

As a reference sample of Quercetin, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
