Chemical Structure
Description
(-)-1,2-Bis((2R,5R)-2,5-diphenylphospholano)ethane 1,2-bis((2R,5R)-2,5-diphenylphospholan-1-yl)ethane 528565-79-9 (CAS 528565-79-9), molecular formula C34H60P2 and molecular weight 530.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, an aromatic ring system, (-)-1,2-Bis((2R,5R)-2,5-diphenylphospholano)ethane 1,2-bis((2R,5R)-2,5-diphenylphospholan-1-yl)ethane 528565-79-9 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 530.79 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.
