Description

As a certified reference material (CRM), 4-[5-(4-methoxyphenyl)-3-phenyl-4,5-dihydro-1h-pyrazol-1-yl]-4-oxobutanoic acid 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.

4-[5-(4-methoxyphenyl)-3-phenyl-4,5-dihydro-1h-pyrazol-1-yl]-4-oxobutanoic acid (CAS 313404-87-4), molecular formula C20H20N2O4 and molecular weight 352.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-[5-(4-methoxyphenyl)-3-phenyl-4,5-dihydro-1h-pyrazol-1-yl]-4-oxobutanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
