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 1-(5-(4-Methoxyphenyl)thiophen-2-yl)ethan-1-one.
CATO supplies 1-(5-(4-Methoxyphenyl)thiophen-2-yl)ethan-1-one (CAS 13918-67-7), a certified reference material (molecular formula C13H12O2S, MW 232.30 g/mol) for analytical method development and quality control.
1-(5-(4-Methoxyphenyl)thiophen-2-yl)ethan-1-one (C13H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
