Chemical Structure

Swertianolin CAS 23445-00-3 chemical structure

Description

Swertianolin (CAS 23445-00-3), molecular formula C20H20O11 and molecular weight 436.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Swertianolin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.37 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 Swertianolin 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.
