Chemical Structure
Description
The occurrence of 10-O-Methylprotosappanin B is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 10-O-Methylprotosappanin B (CAS 111830-77-4), a certified reference material (molecular formula C17H18O6, MW 318.32 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 10-O-Methylprotosappanin B is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.32 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.
CATO manufactures 10-O-Methylprotosappanin 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.
