Chemical Structure
Description
The occurrence of SE-(triphenylgermyl) benzoselenoate 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.
SE-(triphenylgermyl) benzoselenoate (CAS 141858-70-0), molecular formula C18H15GeC7H5OSe and molecular weight 488.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H15GeC7H5OSe, SE-(triphenylgermyl) benzoselenoate 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 488.03 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.
As a certified reference material (CRM), SE-(triphenylgermyl) benzoselenoate 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.
