Chemical Structure
Description
The molecular framework of 1-Methyl-3-(2-methylpyridin-4-yl)-1h-pyrazol-5-amine (C10H12N4) 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.
1-Methyl-3-(2-methylpyridin-4-yl)-1h-pyrazol-5-amine (CAS 1240521-96-3) is a high-purity analytical reference standard with the molecular formula C10H12N4 and a molecular weight of 188.23 g/mol.
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-Methyl-3-(2-methylpyridin-4-yl)-1h-pyrazol-5-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.
