Description
CATO supplies 983-81-3 NSC-132587 NSC132587 Phosphine, (E)- Phosphine, trans- Phosphine,2-ethenediylbis[diphenyl-, (E)- trans-1,2-Bis(diphenylphosphinyl)ethylene trans-Vinylenebis[diphenylphosphine] (CAS 983-81-3), a certified reference material (molecular formula C26H46P2, MW 420.59 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, an aromatic ring system, 983-81-3 NSC-132587 NSC132587 Phosphine, (E)- Phosphine, trans- Phosphine,2-ethenediylbis[diphenyl-, (E)- trans-1,2-Bis(diphenylphosphinyl)ethylene trans-Vinylenebis[diphenylphosphine] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.59 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.
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.
