(1,1-dioxo-1H-benzo[d]isothiazol-3-ylsulfanyl)-acetonitrile 2-((1,1-dioxidobenzo[d]isothiazol-3-yl)thio)acetonitrile 80357-08-0 CAS 80357-08-0

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.

(1,1-dioxo-1H-benzo[d]isothiazol-3-ylsulfanyl)-acetonitrile 2-((1,1-dioxidobenzo[d]isothiazol-3-yl)thio)acetonitrile 80357-08-0 (CAS 80357-08-0) is a high-purity analytical reference standard with the molecular formula C9H6N2O2S2 and a molecular weight of 238.29 g/mol.

Based on its molecular formula C9H6N2O2S2, (1,1-dioxo-1H-benzo[d]isothiazol-3-ylsulfanyl)-acetonitrile 2-((1,1-dioxidobenzo[d]isothiazol-3-yl)thio)acetonitrile 80357-08-0 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
