As a certified reference material (CRM), 5-([1,1'-Biphenyl]-4-yl)-2,4-dihydro-3H-pyrazol-3-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.
CATO supplies 5-([1,1'-Biphenyl]-4-yl)-2,4-dihydro-3H-pyrazol-3-one (CAS 1049128-39-3), a certified reference material (molecular formula C15H12N2O, MW 236.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-([1,1'-Biphenyl]-4-yl)-2,4-dihydro-3H-pyrazol-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
