3-Butyl-1-(3-fluorophenyl)-4,5-dihydro-1H-pyrazol-5-one CAS 1354936-73-4 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 3-Butyl-1-(3-fluorophenyl)-4,5-dihydro-1H-pyrazol-5-one.

3-Butyl-1-(3-fluorophenyl)-4,5-dihydro-1H-pyrazol-5-one (CAS 1354936-73-4) is a high-purity analytical reference standard with the molecular formula C13H15FN2O and a molecular weight of 234.27 g/mol.

3-Butyl-1-(3-fluorophenyl)-4,5-dihydro-1H-pyrazol-5-one (C13H15FN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 3-Butyl-1-(3-fluorophenyl)-4,5-dihydro-1H-pyrazol-5-one 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.
