Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl 2-(3-chloropropanamido)-4-(3,4-dimethylphenyl)thiophene-3-carboxylate (CAS 618395-04-3), a certified reference material (molecular formula C18H20ClNO3S, MW 365.87 g/mol) for analytical method development and quality control.
Ethyl 2-(3-chloropropanamido)-4-(3,4-dimethylphenyl)thiophene-3-carboxylate (C18H20ClNO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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).
CATO manufactures Ethyl 2-(3-chloropropanamido)-4-(3,4-dimethylphenyl)thiophene-3-carboxylate 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.
