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-(pyrrolidin-1-yl)propanamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate oxalate (CAS 1051924-46-9), a certified reference material (molecular formula C18H26N2O3SC2H2O4, MW 440.51 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-(3-(pyrrolidin-1-yl)propanamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate oxalate (C18H26N2O3SC2H2O4) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

CATO manufactures Ethyl 2-(3-(pyrrolidin-1-yl)propanamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate oxalate 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.
