Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
methyl (2S,3S,4S,5R,6S)-3,4,5-triacetoxy-6-[4-(hydroxymethyl)-2-nitro-phenoxy]tetrahydropyran-2-carboxylate (CAS 148579-94-6), molecular formula C20H23NO13 and molecular weight 485.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, methyl (2S,3S,4S,5R,6S)-3,4,5-triacetoxy-6-[4-(hydroxymethyl)-2-nitro-phenoxy]tetrahydropyran-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 485.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures methyl (2S,3S,4S,5R,6S)-3,4,5-triacetoxy-6-[4-(hydroxymethyl)-2-nitro-phenoxy]tetrahydropyran-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
