4-[(1E)-3-(Naphthalen-2-yl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate CAS 331460-46-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(1E)-3-(Naphthalen-2-yl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate.

4-[(1E)-3-(Naphthalen-2-yl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate (CAS 331460-46-9), molecular formula C24H16O3S and molecular weight 384.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 4-[(1E)-3-(Naphthalen-2-yl)-3-oxoprop-1-en-1-yl]phenyl thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.45 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.

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.
