Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
7-Chloro-4-iodobenzo[d]thiazole (CAS 2403783-72-0) is a high-purity analytical reference standard with the molecular formula C7H3ClINS and a molecular weight of 295.53 g/mol.
The molecular framework of 7-Chloro-4-iodobenzo[d]thiazole (C7H3ClINS) is characterized by a nitrile group, sulfur-containing functionality, chlorine/iodine 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. 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.
