1-(3,4-Dimethylphenyl)-1H-pyrazol-4-amine CAS 1707667-84-2

Description

Compared with other compounds in its class, the molecular weight of 187.24 g/mol gives 1-(3,4-Dimethylphenyl)-1H-pyrazol-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3,4-Dimethylphenyl)-1H-pyrazol-4-amine (CAS 1707667-84-2), molecular formula C11H13N3 and molecular weight 187.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3,4-Dimethylphenyl)-1H-pyrazol-4-amine (C11H13N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(3,4-Dimethylphenyl)-1H-pyrazol-4-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.
