Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.10 g/mol gives 6-Iodobenzo[d]isothiazol-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Iodobenzo[d]isothiazol-3-amine (CAS 613262-35-4), a certified reference material (molecular formula C7H5IN2S, MW 276.10 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system, 6-Iodobenzo[d]isothiazol-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
