Chemical Structure
Description
As a certified reference material (CRM), 4-(2-Aminoethyl)-5-(p-tolyl)-1H-pyrazol-3(2H)-one 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.
4-(2-Aminoethyl)-5-(p-tolyl)-1H-pyrazol-3(2H)-one (CAS 910443-41-3) is a high-purity analytical reference standard with the molecular formula C12H15N3O and a molecular weight of 217.27 g/mol.
The molecular framework of 4-(2-Aminoethyl)-5-(p-tolyl)-1H-pyrazol-3(2H)-one (C12H15N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
