5-Bromo-1H-1,2,3-triazole-4-d CAS 1643543-43-4

Description

Compared with other compounds in its class, the molecular weight of 148.97 g/mol gives 5-Bromo-1H-1,2,3-triazole-4-d distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-1H-1,2,3-triazole-4-d (CAS 1643543-43-4) is a high-purity analytical reference standard with the molecular formula C2HDBrN3 and a molecular weight of 148.97 g/mol.

Owing to deuterium isotope labeling, a nitrile group, bromine substitution, 5-Bromo-1H-1,2,3-triazole-4-d is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
