Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 135.56 g/mol gives N-methyl-1H-1,2,3,4-tetrazol-5-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-methyl-1H-1,2,3,4-tetrazol-5-amine hydrochloride (CAS 1444604-63-0), a certified reference material (molecular formula C2H5N5HCl, MW 135.56 g/mol) for analytical method development and quality control.
The molecular framework of N-methyl-1H-1,2,3,4-tetrazol-5-amine hydrochloride (C2H5N5HCl) is characterized by a nitrile group, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
