n-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-2-(4-formyl-2-methoxyphenoxy)acetamide (CAS 838379-75-2), molecular formula C21H21N3O5 and molecular weight 395.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-2-(4-formyl-2-methoxyphenoxy)acetamide (C21H21N3O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
