Chemical Structure
Description
The molecular framework of 3-Amino-1-phenyl-1H-pyrazole-4-carbonitrile (C10H8N4) 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.
3-Amino-1-phenyl-1H-pyrazole-4-carbonitrile (CAS 138942-61-7) is a high-purity analytical reference standard with the molecular formula C10H8N4 and a molecular weight of 184.20 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
