Chemical Structure

(4S)-4,5-Dihydro-4-(1-methylethyl)-2-[2-[(1E)-2-phenylethenyl]phenyl]oxazole CAS 1220093-89-9 chemical structure

Description

The occurrence of (4S)-4,5-Dihydro-4-(1-methylethyl)-2-[2-[(1E)-2-phenylethenyl]phenyl]oxazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4S)-4,5-Dihydro-4-(1-methylethyl)-2-[2-[(1E)-2-phenylethenyl]phenyl]oxazole (CAS 1220093-89-9) is a high-purity analytical reference standard with the molecular formula C20H21NO and a molecular weight of 291.39 g/mol.

(4S)-4,5-Dihydro-4-(1-methylethyl)-2-[2-[(1E)-2-phenylethenyl]phenyl]oxazole (C20H21NO) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
