Description
The occurrence of 1-{[3-(Trifluoromethyl)phenyl]sulfonyl}-2-pyrrolidinecarboxylic acid 1-[[3-(trifluoromethyl)phenyl]sulfonyl]-2-pyrrolidinecarboxylic acid 1-[3-(trifluoromethyl)benzenesulphonyl]pyrrolidine-2-carboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)-2-pyrrolidinecarboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)proline 251096-97-6 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-{[3-(Trifluoromethyl)phenyl]sulfonyl}-2-pyrrolidinecarboxylic acid 1-[[3-(trifluoromethyl)phenyl]sulfonyl]-2-pyrrolidinecarboxylic acid 1-[3-(trifluoromethyl)benzenesulphonyl]pyrrolidine-2-carboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)-2-pyrrolidinecarboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)proline 251096-97-6 (CAS 251096-97-6), a certified reference material (molecular formula C12H12F3NO4S, MW 323.29 g/mol) for analytical method development and quality control.
The molecular framework of 1-{[3-(Trifluoromethyl)phenyl]sulfonyl}-2-pyrrolidinecarboxylic acid 1-[[3-(trifluoromethyl)phenyl]sulfonyl]-2-pyrrolidinecarboxylic acid 1-[3-(trifluoromethyl)benzenesulphonyl]pyrrolidine-2-carboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)-2-pyrrolidinecarboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)proline 251096-97-6 (C12H12F3NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
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.
CATO manufactures 1-{[3-(Trifluoromethyl)phenyl]sulfonyl}-2-pyrrolidinecarboxylic acid 1-[[3-(trifluoromethyl)phenyl]sulfonyl]-2-pyrrolidinecarboxylic acid 1-[3-(trifluoromethyl)benzenesulphonyl]pyrrolidine-2-carboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)-2-pyrrolidinecarboxylic acid 1-([3-(trifluoromethyl)phenyl]sulfonyl)proline 251096-97-6 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.
