Description
CATO supplies (11bS)-4-Hydroxy-2,6-bis(4-nitrophenyl)dinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (CAS 878111-16-1), a certified reference material (molecular formula C32H19N2O8P, MW 590.48 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, (11bS)-4-Hydroxy-2,6-bis(4-nitrophenyl)dinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 590.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
