Chemical Structure
Description
Structurally, Benzo[c]isothiazol-4-amine (C7H6N2S) contains a nitrile group, sulfur-containing functionality, 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 150.20 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Benzo[c]isothiazol-4-amine (CAS 56910-92-0) is a high-purity analytical reference standard with the molecular formula C7H6N2S and a molecular weight of 150.20 g/mol.
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.
