Chemical Structure
Description
Bis(1,5-cyclooctadiene)bis(μ-diphenylphosphido)dirhodium (CAS 82829-24-1) is a high-purity analytical reference standard with the molecular formula C40H36P2Rh2 and a molecular weight of 784.47 g/mol.
Owing to organophosphorus functionality, a polycyclic aromatic system, Bis(1,5-cyclooctadiene)bis(μ-diphenylphosphido)dirhodium is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 784.47 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.
CATO manufactures Bis(1,5-cyclooctadiene)bis(μ-diphenylphosphido)dirhodium under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
