Chemical Structure
Description
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.
3-Phenyl-2-(thiophen-2-yl)propanoic acid (CAS 91902-78-2), molecular formula C3H6N4O2CH4O3S and molecular weight 226.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Phenyl-2-(thiophen-2-yl)propanoic acid (C3H6N4O2CH4O3S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
