Chemical Structure

1-(3-methyl-1H-1,2,4-triazol-5-yl)piperazine dihydrochloride CAS 1909320-03-1 chemical structure

Description

Owing to a nitrile group, chlorine substitution, 1-(3-methyl-1H-1,2,4-triazol-5-yl)piperazine dihydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.67 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).

1-(3-methyl-1H-1,2,4-triazol-5-yl)piperazine dihydrochloride (CAS 1909320-03-1) is a high-purity analytical reference standard with the molecular formula C7H13N5HCl and a molecular weight of 203.67 g/mol.

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.
