Description
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.
CATO supplies 4-Oxo-4-phenyl-N-(1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-pyrazol-4-yl)butanamide (CAS 1705096-75-8), a certified reference material (molecular formula C19H23N3O3, MW 341.40 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H23N3O3, 4-Oxo-4-phenyl-N-(1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-pyrazol-4-yl)butanamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 341.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
