5-Chloro-4-((pyridin-2-ylthio)methyl)-1,2,3-thiadiazole (CAS 338761-26-5), molecular formula C8H6ClN3S2 and molecular weight 243.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-4-((pyridin-2-ylthio)methyl)-1,2,3-thiadiazole (C8H6ClN3S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
