Description
CATO supplies 3-Amino-N-(2-chlorophenyl)-6-ethyl-5-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (CAS 664999-38-6), a certified reference material (molecular formula C18H15ClF3N3OS, MW 413.84 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-Amino-N-(2-chlorophenyl)-6-ethyl-5-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 3-Amino-N-(2-chlorophenyl)-6-ethyl-5-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-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.
