CATO supplies Ethyl 2-(2-((3-cyano-6-methyl-4-(thiophen-3-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 387831-30-3), a certified reference material (molecular formula C27H28N4O3S3, MW 552.73 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-(2-((3-cyano-6-methyl-4-(thiophen-3-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C27H28N4O3S3) is characterized by a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Ethyl 2-(2-((3-cyano-6-methyl-4-(thiophen-3-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
