Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 176.61 g/mol gives 5-amino-1-methyl-1H-1,2,3-triazole-4-carboximidamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-amino-1-methyl-1H-1,2,3-triazole-4-carboximidamide hydrochloride (CAS 55432-72-9) is a high-purity analytical reference standard with the molecular formula C4H8N6HCl and a molecular weight of 176.61 g/mol.
The molecular framework of 5-amino-1-methyl-1H-1,2,3-triazole-4-carboximidamide hydrochloride (C4H8N6HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
