CATO supplies Ethyl 2-(2-{[3-cyano-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl]sulfanyl}acetamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (CAS 445383-33-5), a certified reference material (molecular formula C27H28N4O3S3, MW 552.73 g/mol) for analytical method development and quality control.
Ethyl 2-(2-{[3-cyano-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl]sulfanyl}acetamido)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (C27H28N4O3S3) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
