4-Hydroxy-1-phenyl-1h-pyrazole-3-carbohydrazide CAS 956781-13-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxy-1-phenyl-1h-pyrazole-3-carbohydrazide.

4-Hydroxy-1-phenyl-1h-pyrazole-3-carbohydrazide (CAS 956781-13-8) is a high-purity analytical reference standard with the molecular formula C10H10N4O2 and a molecular weight of 218.21 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Hydroxy-1-phenyl-1h-pyrazole-3-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-Hydroxy-1-phenyl-1h-pyrazole-3-carbohydrazide 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.
