Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Phenyl-3-(o-tolyl)-1h-pyrazol-5-amine.
CATO supplies 1-Phenyl-3-(o-tolyl)-1h-pyrazol-5-amine (CAS 618092-66-3), a certified reference material (molecular formula C16H15N3, MW 249.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H15N3, 1-Phenyl-3-(o-tolyl)-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 249.31 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.
As a certified reference material (CRM), 1-Phenyl-3-(o-tolyl)-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.
