Description
As a certified reference material (CRM), 5-Amino-3-benzyl-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.
5-Amino-3-benzyl-1h-pyrazole-4-carbonitrile (CAS 42754-64-3) is a high-purity analytical reference standard with the molecular formula C11H10N4 and a molecular weight of 198.22 g/mol.
The molecular framework of 5-Amino-3-benzyl-1h-pyrazole-4-carbonitrile (C11H10N4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
