Chemical Structure
Description
2-Thiophenecarboxylic acid, 5-amino-3-cyclopropyl-, methyl ester (CAS 851443-16-8), molecular formula C9H11NO2S and molecular weight 197.25 g/mol, is a CATO reference standard with documented purity and traceability.
2-Thiophenecarboxylic acid, 5-amino-3-cyclopropyl-, methyl ester (C9H11NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2-Thiophenecarboxylic acid, 5-amino-3-cyclopropyl-, methyl ester 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.
