Chemical Structure

4-Fluoro-1H-pyrazole hydrochloride CAS 1951440-89-3 chemical structure

Description

As a certified reference material (CRM), 4-Fluoro-1H-pyrazole 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.

CATO supplies 4-Fluoro-1H-pyrazole hydrochloride (CAS 1951440-89-3), a certified reference material (molecular formula C3H3FN2HCl, MW 122.53 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine/chlorine substitution, 4-Fluoro-1H-pyrazole hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.53 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.
