Chemical Structure

3-(8-Methoxy-2-oxo-2H-chromen-3-yl)propanoic acid CAS 1365940-75-5 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 3-(8-Methoxy-2-oxo-2H-chromen-3-yl)propanoic acid.

CATO supplies 3-(8-Methoxy-2-oxo-2H-chromen-3-yl)propanoic acid (CAS 1365940-75-5), a certified reference material (molecular formula C13H12O5, MW 248.23 g/mol) for analytical method development and quality control.

The molecular framework of 3-(8-Methoxy-2-oxo-2H-chromen-3-yl)propanoic acid (C13H12O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-(8-Methoxy-2-oxo-2H-chromen-3-yl)propanoic 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.
