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.
2-(3-(4-Methoxyphenyl)-4-(prop-1-en-2-yl)isoxazol-5-yl)propan-2-ol (CAS 890092-95-2) is a high-purity analytical reference standard with the molecular formula C16H19NO3 and a molecular weight of 273.33 g/mol.
The molecular framework of 2-(3-(4-Methoxyphenyl)-4-(prop-1-en-2-yl)isoxazol-5-yl)propan-2-ol (C16H19NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
