3-(3,5-Dimethyl-4-isoxazolyl)-5-hydroxy-α-phenyl-benzenemethanol CAS 1429129-68-9

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.

3-(3,5-Dimethyl-4-isoxazolyl)-5-hydroxy-α-phenyl-benzenemethanol (CAS 1429129-68-9) is a high-purity analytical reference standard with the molecular formula C18H17NO3 and a molecular weight of 295.33 g/mol.

Based on its molecular formula C18H17NO3, 3-(3,5-Dimethyl-4-isoxazolyl)-5-hydroxy-α-phenyl-benzenemethanol 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 295.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
