Chemical Structure
Description
CATO supplies 5-Acetyl-N,N-dimethylthiophene-2-carboxamide (CAS 77779-14-7), a certified reference material (molecular formula C9H11NO2S, MW 197.25 g/mol) for analytical method development and quality control.
5-Acetyl-N,N-dimethylthiophene-2-carboxamide (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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 5-Acetyl-N,N-dimethylthiophene-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.
