5-[3-(3,4-dimethoxyphenyl)-5-(furan-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]-5-oxopentanoic acid CAS 799258-14-3 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 5-[3-(3,4-dimethoxyphenyl)-5-(furan-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]-5-oxopentanoic acid.

5-[3-(3,4-dimethoxyphenyl)-5-(furan-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]-5-oxopentanoic acid (CAS 799258-14-3), molecular formula C20H22N2O6 and molecular weight 386.40 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, 5-[3-(3,4-dimethoxyphenyl)-5-(furan-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]-5-oxopentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.40 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), 5-[3-(3,4-dimethoxyphenyl)-5-(furan-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]-5-oxopentanoic 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.
