1-(2,4-dimethylphenyl)-3-phenyl-1H-pyrazol-5-amine CAS 956751-68-1

Description

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.

1-(2,4-dimethylphenyl)-3-phenyl-1H-pyrazol-5-amine (CAS 956751-68-1), molecular formula C17H17N3 and molecular weight 263.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-(2,4-dimethylphenyl)-3-phenyl-1H-pyrazol-5-amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.34 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).

CATO manufactures 1-(2,4-dimethylphenyl)-3-phenyl-1H-pyrazol-5-amine 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.
