Chemical Structure

5-Oxo-3-phenyl-2,5-dihydro-1H-pyrazole-1-carboximidamide CAS 861206-89-5 chemical structure

Description

As a certified reference material (CRM), 5-Oxo-3-phenyl-2,5-dihydro-1H-pyrazole-1-carboximidamide 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-Oxo-3-phenyl-2,5-dihydro-1H-pyrazole-1-carboximidamide (CAS 861206-89-5) is a high-purity analytical reference standard with the molecular formula C10H10N4O and a molecular weight of 202.21 g/mol.

The molecular framework of 5-Oxo-3-phenyl-2,5-dihydro-1H-pyrazole-1-carboximidamide (C10H10N4O) 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 the protonation state of its nitrogen-containing groups, 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.
