Chemical Structure
Description
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.
4-(3,5-Diethyl-1H-pyrazol-1-yl)-3-methylaniline (CAS 481068-97-7), molecular formula C14H19N3 and molecular weight 229.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3,5-Diethyl-1H-pyrazol-1-yl)-3-methylaniline (C14H19N3) 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.
As a certified reference material (CRM), 4-(3,5-Diethyl-1H-pyrazol-1-yl)-3-methylaniline 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.
