Chemical Structure
Description
The molecular framework of 2-(chloromethyl)-5-(propan-2-yl)-1,3,4-thiadiazole (C6H9ClN2S) is characterized by 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. 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).
2-(chloromethyl)-5-(propan-2-yl)-1,3,4-thiadiazole (CAS 1260670-84-5) is a high-purity analytical reference standard with the molecular formula C6H9ClN2S and a molecular weight of 176.67 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
