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 3-[4,6-Dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridin-2-yl]-1-[3-(trifluoromethyl)phenyl]urea (CAS 672950-55-9), a certified reference material (molecular formula C21H17F3N4OS, MW 430.45 g/mol) for analytical method development and quality control.
The molecular framework of 3-[4,6-Dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridin-2-yl]-1-[3-(trifluoromethyl)phenyl]urea (C21H17F3N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3-[4,6-Dimethyl-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridin-2-yl]-1-[3-(trifluoromethyl)phenyl]urea 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.
