(4Z)-3-tert-Butyl-4-[(naphthalen-1-yl)methylidene]-1-phenyl-4,5-dihydro-1H-pyrazol-5-one CAS 1024754-31-1

Description

(4Z)-3-tert-Butyl-4-[(naphthalen-1-yl)methylidene]-1-phenyl-4,5-dihydro-1H-pyrazol-5-one (C24H22N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(4Z)-3-tert-Butyl-4-[(naphthalen-1-yl)methylidene]-1-phenyl-4,5-dihydro-1H-pyrazol-5-one (CAS 1024754-31-1) is a high-purity analytical reference standard with the molecular formula C24H22N2O and a molecular weight of 354.44 g/mol.

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.
