2-(5,9-Dimethyl-7-oxo-3-phenyl-7h-furo[3,2-g]chromen-6-yl)acetic acid CAS 664366-12-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5,9-Dimethyl-7-oxo-3-phenyl-7h-furo[3,2-g]chromen-6-yl)acetic acid.

2-(5,9-Dimethyl-7-oxo-3-phenyl-7h-furo[3,2-g]chromen-6-yl)acetic acid (CAS 664366-12-5), molecular formula C21H16O5 and molecular weight 348.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-(5,9-Dimethyl-7-oxo-3-phenyl-7h-furo[3,2-g]chromen-6-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.35 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.

As a certified reference material (CRM), 2-(5,9-Dimethyl-7-oxo-3-phenyl-7h-furo[3,2-g]chromen-6-yl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
