Chemical Structure

3-Chloro-1-methyl-1H-pyrazol-5-amine hydrochloride CAS 1312949-22-6 chemical structure

Description

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.

3-Chloro-1-methyl-1H-pyrazol-5-amine hydrochloride (CAS 1312949-22-6) is a high-purity analytical reference standard with the molecular formula C4H6ClN3HCl and a molecular weight of 168.02 g/mol.

Structurally, 3-Chloro-1-methyl-1H-pyrazol-5-amine hydrochloride (C4H6ClN3HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 168.02 g/mol, it falls into the medium-molecular-weight range. 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.
