Chemical Structure
Description
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.
N-((5-(Furan-2-yl)isoxazol-3-yl)methyl)-3,3-diphenylpropanamide (CAS 1105205-20-6) is a high-purity analytical reference standard with the molecular formula C23H20N2O3 and a molecular weight of 372.42 g/mol.
The molecular framework of N-((5-(Furan-2-yl)isoxazol-3-yl)methyl)-3,3-diphenylpropanamide (C23H20N2O3) is characterized by a steroid 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).
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.
