Description
CATO manufactures N-(4-Chlorophenyl)thiophene-2-carboxamide 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.
CATO supplies N-(4-Chlorophenyl)thiophene-2-carboxamide (CAS 15950-35-3), a certified reference material (molecular formula C11H8ClNOS, MW 237.71 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-Chlorophenyl)thiophene-2-carboxamide (C11H8ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
