4-Bromothiophene-2-thiol CAS 88982-27-8

Description

Compared with other compounds in its class, the molecular weight of 195.10 g/mol gives 4-Bromothiophene-2-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromothiophene-2-thiol (CAS 88982-27-8) is a high-purity analytical reference standard with the molecular formula C4H3BrS2 and a molecular weight of 195.10 g/mol.

The molecular framework of 4-Bromothiophene-2-thiol (C4H3BrS2) is characterized by sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
