Chemical Structure

1-(3-Chlorophenyl)-3-methyl-1H-pyrazol-5-amine CAS 40401-41-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 207.66 g/mol gives 1-(3-Chlorophenyl)-3-methyl-1H-pyrazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(3-Chlorophenyl)-3-methyl-1H-pyrazol-5-amine (CAS 40401-41-0), a certified reference material (molecular formula C10H10ClN3, MW 207.66 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(3-Chlorophenyl)-3-methyl-1H-pyrazol-5-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-(3-Chlorophenyl)-3-methyl-1H-pyrazol-5-amine 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.
