Description
As a certified reference material (CRM), 2-chloro-6-iodobenzo[d]thiazole 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.
2-chloro-6-iodobenzo[d]thiazole (CAS 855282-75-6) is a high-purity analytical reference standard with the molecular formula C7H3ClINS and a molecular weight of 295.53 g/mol.
2-chloro-6-iodobenzo[d]thiazole (C7H3ClINS) contains a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
