Chemical Structure

1-(difluoromethyl)-1H-pyrazol-3-amine hydrochloride CAS 919785-20-9 chemical structure

Description

CATO supplies 1-(difluoromethyl)-1H-pyrazol-3-amine hydrochloride (CAS 919785-20-9), a certified reference material (molecular formula C4H5F2N3HCl, MW 169.56 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine/chlorine substitution, 1-(difluoromethyl)-1H-pyrazol-3-amine hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 1-(difluoromethyl)-1H-pyrazol-3-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
