Chemical Structure
Description
The molecular framework of N-(4-((2-chlorophenyl)sulfonyl)phenyl)-2,6-difluorobenzamide (C19H12ClF2NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies N-(4-((2-chlorophenyl)sulfonyl)phenyl)-2,6-difluorobenzamide (CAS 339105-40-7), a certified reference material (molecular formula C19H12ClF2NO3S, MW 407.82 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(4-((2-chlorophenyl)sulfonyl)phenyl)-2,6-difluorobenzamide 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.
