Description
CATO manufactures 5-(1-(3,4-Dimethoxy-5-(methylselanyl)phenyl)vinyl)-2-methoxyphenyl dihydrogen phosphate 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.
5-(1-(3,4-Dimethoxy-5-(methylselanyl)phenyl)vinyl)-2-methoxyphenyl dihydrogen phosphate (CAS 2123478-22-6) is a high-purity analytical reference standard with the molecular formula C18H21O7PSe and a molecular weight of 459.29 g/mol.
Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, 5-(1-(3,4-Dimethoxy-5-(methylselanyl)phenyl)vinyl)-2-methoxyphenyl dihydrogen phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 459.29 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
