Description
As a certified reference material (CRM), (3,5-Dimethyl-4-((phenylsulfonyl)methyl)-1H-pyrazol-1-yl)(3-(trifluoromethyl)phenyl)methanone 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.
(3,5-Dimethyl-4-((phenylsulfonyl)methyl)-1H-pyrazol-1-yl)(3-(trifluoromethyl)phenyl)methanone (CAS 324009-24-7), molecular formula C20H17F3N2O3S and molecular weight 422.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3,5-Dimethyl-4-((phenylsulfonyl)methyl)-1H-pyrazol-1-yl)(3-(trifluoromethyl)phenyl)methanone (C20H17F3N2O3S) is characterized by a steroid core, an amide group, a sulfone group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
