Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 430.71 g/mol gives DL-Tocopherol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DL-Tocopherol (CAS 2074-53-5), molecular formula C29H50O2 and molecular weight 430.71 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C29H50O2, DL-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 430.71 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures DL-Tocopherol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
