2,6-Dichloro-5-fluorobenzothiazole (CAS 927827-69-8) is a high-purity analytical reference standard with the molecular formula C7H2Cl2FNS and a molecular weight of 222.07 g/mol.
The molecular framework of 2,6-Dichloro-5-fluorobenzothiazole (C7H2Cl2FNS) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. 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).
As a certified reference material (CRM), 2,6-Dichloro-5-fluorobenzothiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
