Chemical Structure

1-Methyl-1h-pyrazol-5-amine hydrochloride CAS 32016-34-5 chemical structure

Description

CATO supplies 1-Methyl-1h-pyrazol-5-amine hydrochloride (CAS 32016-34-5), a certified reference material (molecular formula C4H7N3HCl, MW 133.58 g/mol) for analytical method development and quality control.

Structurally, 1-Methyl-1h-pyrazol-5-amine hydrochloride (C4H7N3HCl) 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 133.58 g/mol, it falls into the low-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.

As a certified reference material (CRM), 1-Methyl-1h-pyrazol-5-amine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
