Chemical Structure
Description
4-[(Thiophen-2-ylmethyl)-amino]-benzoic acid (CAS 451498-55-8), molecular formula C13H13NO2S and molecular weight 247.31 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(Thiophen-2-ylmethyl)-amino]-benzoic acid (C13H13NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-[(Thiophen-2-ylmethyl)-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.
