CATO supplies 5-(Chloromethyl)-2-[3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl]pyrazolo[1,5-a]pyrimidin-7-ol (CAS 478259-04-0), a certified reference material (molecular formula C17H15ClN4OS, MW 358.85 g/mol) for analytical method development and quality control.
The molecular framework of 5-(Chloromethyl)-2-[3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl]pyrazolo[1,5-a]pyrimidin-7-ol (C17H15ClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
