Description
As a certified reference material (CRM), diphenyl diselenide 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.
diphenyl diselenide (CAS 1666-13-3) is a high-purity analytical reference standard with the molecular formula C12H22Se2 and a molecular weight of 324.22 g/mol.
Based on its molecular formula C12H22Se2, diphenyl diselenide contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 324.22 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.
