Chemical Structure
Description
The occurrence of 2-Chloro-N-{4-[(4-fluorophenyl)sulfanyl]phenyl}-4-methanesulfonylbenzamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-N-{4-[(4-fluorophenyl)sulfanyl]phenyl}-4-methanesulfonylbenzamide (CAS 339011-57-3), molecular formula C20H15ClFNO3S2 and molecular weight 435.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-N-{4-[(4-fluorophenyl)sulfanyl]phenyl}-4-methanesulfonylbenzamide (C20H15ClFNO3S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-Chloro-N-{4-[(4-fluorophenyl)sulfanyl]phenyl}-4-methanesulfonylbenzamide 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.
