Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.04 g/mol gives Diphenyldiethyltin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diphenyldiethyltin (CAS 10203-52-8), molecular formula C16H20Sn and molecular weight 331.04 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H20Sn, Diphenyldiethyltin contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.04 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), Diphenyldiethyltin 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.
