Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-{[(5-chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)methyl]sulfanyl}benzoic acid (CAS 318234-17-2), a certified reference material (molecular formula C18H15ClN2O2S, MW 358.84 g/mol) for analytical method development and quality control.
The molecular framework of 2-{[(5-chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)methyl]sulfanyl}benzoic acid (C18H15ClN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-{[(5-chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)methyl]sulfanyl}benzoic acid 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.
