Description
(11bS)-N-[(1R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydro-1-naphthalenyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 960240-31-7), molecular formula C42H33NO2P2 and molecular weight 645.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (11bS)-N-[(1R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydro-1-naphthalenyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 645.66 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.
As a certified reference material (CRM), (11bS)-N-[(1R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydro-1-naphthalenyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
