(s)-3-Amino-3-(4-chlorothiophen-2-yl)propanoic acid CAS 1366563-92-9

Description

Compared with other compounds in its class, the molecular weight of 205.66 g/mol gives (s)-3-Amino-3-(4-chlorothiophen-2-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(s)-3-Amino-3-(4-chlorothiophen-2-yl)propanoic acid (CAS 1366563-92-9), molecular formula C7H8ClNO2S and molecular weight 205.66 g/mol, is a CATO reference standard with documented purity and traceability.

(s)-3-Amino-3-(4-chlorothiophen-2-yl)propanoic acid (C7H8ClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
