3,5-dimethyl-1-(4-methylphenyl)-1H-pyrazol-4-amine CAS 63203-92-9

Description

Compared with other compounds in its class, the molecular weight of 201.27 g/mol gives 3,5-dimethyl-1-(4-methylphenyl)-1H-pyrazol-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-dimethyl-1-(4-methylphenyl)-1H-pyrazol-4-amine (CAS 63203-92-9) is a high-purity analytical reference standard with the molecular formula C12H15N3 and a molecular weight of 201.27 g/mol.

The molecular framework of 3,5-dimethyl-1-(4-methylphenyl)-1H-pyrazol-4-amine (C12H15N3) 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
