Chemical Structure

Sodium (S)-2-oxo-3-(3-oxo-1-phenylbutyl)-2H-chromen-4-olate CAS 5543-79-3 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 Sodium (S)-2-oxo-3-(3-oxo-1-phenylbutyl)-2H-chromen-4-olate.

CATO supplies Sodium (S)-2-oxo-3-(3-oxo-1-phenylbutyl)-2H-chromen-4-olate (CAS 5543-79-3), a certified reference material (molecular formula C19H15NaO4, MW 330.31 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Sodium (S)-2-oxo-3-(3-oxo-1-phenylbutyl)-2H-chromen-4-olate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Sodium (S)-2-oxo-3-(3-oxo-1-phenylbutyl)-2H-chromen-4-olate 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.
