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 5-Amino-1-(4-isopropylphenyl)-1H-pyrazole-4-carbonitrile.
5-Amino-1-(4-isopropylphenyl)-1H-pyrazole-4-carbonitrile (CAS 1175899-74-7), molecular formula C13H14N4 and molecular weight 226.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Amino-1-(4-isopropylphenyl)-1H-pyrazole-4-carbonitrile (C13H14N4) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Amino-1-(4-isopropylphenyl)-1H-pyrazole-4-carbonitrile 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.
