5-(4-Bromophenyl)-1-(o-tolyl)-1h-imidazole-2-thiol CAS 1105190-06-4

Description

The occurrence of 5-(4-Bromophenyl)-1-(o-tolyl)-1h-imidazole-2-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(4-Bromophenyl)-1-(o-tolyl)-1h-imidazole-2-thiol (CAS 1105190-06-4), molecular formula C16H13BrN2S and molecular weight 345.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(4-Bromophenyl)-1-(o-tolyl)-1h-imidazole-2-thiol (C16H13BrN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 345.26 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
