Chemical Structure
Description
The occurrence of DL-alpha-Tocopherol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
DL-alpha-Tocopherol (CAS 10191-41-0) is a high-purity analytical reference standard with the molecular formula C29H50O2 and a molecular weight of 430.71 g/mol.
Structurally, DL-alpha-Tocopherol (C29H50O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 430.71 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
