(4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-(phenylmethyl)-2-oxazolidinone (4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-benzyl-2-oxazolidinone 548783-48-8 CAS 548783-48-8 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.

CATO supplies (4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-(phenylmethyl)-2-oxazolidinone (4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-benzyl-2-oxazolidinone 548783-48-8 (CAS 548783-48-8), a certified reference material (molecular formula C21H29NO3, MW 343.46 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H29NO3, (4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-(phenylmethyl)-2-oxazolidinone (4R)-3-[(2S)-1-Oxo-2-(2-propenyl)octyl]-4-benzyl-2-oxazolidinone 548783-48-8 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 343.46 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.

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.
