Uvarigranol B CAS 164204-79-9 chemical structure

Description

CATO manufactures Uvarigranol B 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.

Uvarigranol B (CAS 164204-79-9), molecular formula C23H22O8 and molecular weight 426.42 g/mol, is a CATO reference standard with documented purity and traceability.

Uvarigranol B (C23H22O8) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
