Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 472.74 g/mol gives D-Alfa-Tocopherol Acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
D-Alfa-Tocopherol Acetate (CAS 58-95-7), molecular formula C31H52O3 and molecular weight 472.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, D-Alfa-Tocopherol Acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 D-Alfa-Tocopherol Acetate 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.
