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.
CATO supplies 7-Iodobenzo[d]isothiazole (CAS 139036-99-0), a certified reference material (molecular formula C7H4INS, MW 261.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H4INS, 7-Iodobenzo[d]isothiazole contains a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
