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-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)acetic acid (CAS 338422-73-4) is a high-purity analytical reference standard with the molecular formula C8H5ClF3NO2S and a molecular weight of 271.64 g/mol.
2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)acetic acid (C8H5ClF3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)acetic 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.
