Chemical Structure

5-Bromo-3-isopropylisothiazole-4-carbonitrile CAS 1823933-86-3 chemical structure

Description

The occurrence of 5-Bromo-3-isopropylisothiazole-4-carbonitrile is closely related to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-3-isopropylisothiazole-4-carbonitrile (CAS 1823933-86-3), molecular formula C7H7BrN2S and molecular weight 231.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Bromo-3-isopropylisothiazole-4-carbonitrile (C7H7BrN2S) contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 231.11 g/mol, it falls into the medium-molecular-weight range. 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.

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.
