Chemical Structure
Description
b-Tocopherol-d3(major) (CAS 936230-75-0) is a high-purity analytical reference standard with the molecular formula C28H45D3O2 and a molecular weight of 419.70 g/mol.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, b-Tocopherol-d3(major) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.70 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.
As a certified reference material (CRM), b-Tocopherol-d3(major) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
