Chemical Structure
Description
5-Iodobenzo[d]isothiazole (CAS 1174534-50-9), molecular formula C7H4INS and molecular weight 261.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Iodobenzo[d]isothiazole (C7H4INS) contains a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 261.08 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
