CATO manufactures 5-{[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]methyl}-2-thiophenesulfonohydrazide 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.
5-{[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]methyl}-2-thiophenesulfonohydrazide (CAS 306976-75-0), molecular formula C11H9ClF3N3O2S2 and molecular weight 371.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-{[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]methyl}-2-thiophenesulfonohydrazide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
