Chemical Structure

Ophiopogonoside A CAS 791849-22-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ophiopogonoside A.

Ophiopogonoside A (CAS 791849-22-4) is a high-purity analytical reference standard with the molecular formula C21H38O8 and a molecular weight of 418.52 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ophiopogonoside A is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.52 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Ophiopogonoside A 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.
