4-(5-(4-(Dimethylamino)phenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-oxobutanoic acid CAS 394225-50-4

Description

The occurrence of 4-(5-(4-(Dimethylamino)phenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-oxobutanoic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(5-(4-(Dimethylamino)phenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-oxobutanoic acid (CAS 394225-50-4), molecular formula C21H23N3O3 and molecular weight 365.43 g/mol, is a CATO reference standard with documented purity and traceability.

4-(5-(4-(Dimethylamino)phenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-oxobutanoic acid (C21H23N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
