Description
CATO supplies 2K-539S 338774-50-8 6-amino-2-hydroxy-5-[3-(trifluoromethyl)benzenesulfonyl]pyridine-3-carbonitrile (CAS 338774-50-8), a certified reference material (molecular formula C13H8F3N3O3S, MW 343.28 g/mol) for analytical method development and quality control.
The molecular framework of 2K-539S 338774-50-8 6-amino-2-hydroxy-5-[3-(trifluoromethyl)benzenesulfonyl]pyridine-3-carbonitrile (C13H8F3N3O3S) 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.
As a certified reference material (CRM), 2K-539S 338774-50-8 6-amino-2-hydroxy-5-[3-(trifluoromethyl)benzenesulfonyl]pyridine-3-carbonitrile 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.
