Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.61 g/mol gives 4-(4-bromophenyl)-2-hydrazino-1,3-thiazole,HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(4-bromophenyl)-2-hydrazino-1,3-thiazole,HCl (CAS 4871-23-2), a certified reference material (molecular formula C9H8BrN3SHCl, MW 306.61 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-bromophenyl)-2-hydrazino-1,3-thiazole,HCl (C9H8BrN3SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
