Chemical Structure

(S)-2-Acetamido-3-(3-chlorophenyl)propanoic acid CAS 197087-51-7 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.

(S)-2-Acetamido-3-(3-chlorophenyl)propanoic acid (CAS 197087-51-7), molecular formula C11H12ClNO3 and molecular weight 241.67 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-2-Acetamido-3-(3-chlorophenyl)propanoic acid (C11H12ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
