Chemical Structure
Description
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.
4-[({5-[(4-Chlorophenoxy)methyl]-1,3,4-thiadiazol-2-yl}carbonyl)amino]benzoic acid (CAS 1142202-91-2), molecular formula C17H12ClN3O4S and molecular weight 389.81 g/mol, is a CATO reference standard with documented purity and traceability.
4-[({5-[(4-Chlorophenoxy)methyl]-1,3,4-thiadiazol-2-yl}carbonyl)amino]benzoic acid (C17H12ClN3O4S) contains a flavonoid core, 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, 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.
CATO manufactures 4-[({5-[(4-Chlorophenoxy)methyl]-1,3,4-thiadiazol-2-yl}carbonyl)amino]benzoic 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.
