Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl 4-methylbenzene-1-sulfonate (CAS 337919-83-2), molecular formula C19H13ClF3NO4S and molecular weight 443.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl 4-methylbenzene-1-sulfonate (C19H13ClF3NO4S) is characterized by a flavonoid 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 the protonation state of its nitrogen-containing groups, 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.
CATO manufactures 3-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl 4-methylbenzene-1-sulfonate 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.
