Chemical Structure

Beta-Tocopherol CAS 148-03-8 chemical structure

Description

Based on its molecular formula C28H48O2, Beta-Tocopherol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 416.68 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.

Beta-Tocopherol (CAS 148-03-8) is a high-purity analytical reference standard with the molecular formula C28H48O2 and a molecular weight of 416.68 g/mol.

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.
