Chemical Structure
Description
CATO supplies 3-(2,5-dimethylphenyl)-1H-pyrazol-5-amine (CAS 501902-68-7), a certified reference material (molecular formula C11H13N3, MW 187.24 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H13N3, 3-(2,5-dimethylphenyl)-1H-pyrazol-5-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 187.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures 3-(2,5-dimethylphenyl)-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.
