2-(4-(Methylthio)phenyl)propanoic acid CAS 1368885-47-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-(Methylthio)phenyl)propanoic acid.

2-(4-(Methylthio)phenyl)propanoic acid (CAS 1368885-47-5), molecular formula C10H12O2S and molecular weight 196.27 g/mol, is a CATO reference standard with documented purity and traceability.

2-(4-(Methylthio)phenyl)propanoic acid (C10H12O2S) 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.
