Chemical Structure

1-Methyl-5-phenyl-1H-pyrazol-3-amine CAS 85485-60-5 chemical structure

Description

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.

1-Methyl-5-phenyl-1H-pyrazol-3-amine (CAS 85485-60-5), molecular formula C10H11N3 and molecular weight 173.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H11N3, 1-Methyl-5-phenyl-1H-pyrazol-3-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
