Description

CATO manufactures 5-(2-Chlorobenzamido)-3-methylthiophene-2-carboxylic 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.

5-(2-Chlorobenzamido)-3-methylthiophene-2-carboxylic acid (CAS 926228-57-1), molecular formula C13H10ClNO3S and molecular weight 295.74 g/mol, is a CATO reference standard with documented purity and traceability.

5-(2-Chlorobenzamido)-3-methylthiophene-2-carboxylic acid (C13H10ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
