Description
As a certified reference material (CRM), 5-(4-Isobutylphenyl)-2H-pyrazol-3-ylamine 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.
5-(4-Isobutylphenyl)-2H-pyrazol-3-ylamine (CAS 501902-78-9), molecular formula C13H17N3 and molecular weight 215.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-Isobutylphenyl)-2H-pyrazol-3-ylamine (C13H17N3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
