Chemical Structure
Description
Owing to an organic framework, Diphenyl selenyl ether is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 245.26 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.
Diphenyl selenyl ether (CAS 1132-39-4) is a high-purity analytical reference standard with the molecular formula C12H22Se and a molecular weight of 245.26 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
