4-[(1Z)-3-(4-Methoxyphenyl)-3-oxoprop-1-en-1-yl]phenyl 4-methylbenzoate CAS 331461-43-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(1Z)-3-(4-Methoxyphenyl)-3-oxoprop-1-en-1-yl]phenyl 4-methylbenzoate.

CATO supplies 4-[(1Z)-3-(4-Methoxyphenyl)-3-oxoprop-1-en-1-yl]phenyl 4-methylbenzoate (CAS 331461-43-9), a certified reference material (molecular formula C24H20O4, MW 372.41 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 4-[(1Z)-3-(4-Methoxyphenyl)-3-oxoprop-1-en-1-yl]phenyl 4-methylbenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
