Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (5R,6R)-5,6-Bis(diphenylphosphanyl)bicyclo[2.2.1]hept-2-ene (CAS 321898-68-4), a certified reference material (molecular formula C31H28P2, MW 462.50 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a polycyclic aromatic system, (5R,6R)-5,6-Bis(diphenylphosphanyl)bicyclo[2.2.1]hept-2-ene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
