2-((4-Chlorophenyl)thio)propanoic acid CAS 18527-12-3

Description

The occurrence of 2-((4-Chlorophenyl)thio)propanoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Chlorophenyl)thio)propanoic acid (CAS 18527-12-3), molecular formula C9H9ClO2S and molecular weight 216.68 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Chlorophenyl)thio)propanoic acid (C9H9ClO2S) contains 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.

CATO manufactures 2-((4-Chlorophenyl)thio)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
