Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-({[(2,4-difluorophenyl)carbamoyl]methyl}sulfanyl)acetic acid (CAS 338793-67-2), molecular formula C10H9F2NO3S and molecular weight 261.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-({[(2,4-difluorophenyl)carbamoyl]methyl}sulfanyl)acetic acid (C10H9F2NO3S) 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 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.
As a certified reference material (CRM), 2-({[(2,4-difluorophenyl)carbamoyl]methyl}sulfanyl)acetic acid 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.
