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 2-Amino-1-(4-methoxythiophen-2-yl)ethan-1-one.
2-Amino-1-(4-methoxythiophen-2-yl)ethan-1-one (CAS 1520772-55-7), molecular formula C7H9NO2S and molecular weight 171.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Amino-1-(4-methoxythiophen-2-yl)ethan-1-one (C7H9NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
