Chemical Structure

N-[2-[(3aR,8aS)-3a,8a-Dihydro-8H-indeno[1,2-d]oxazol-2-yl]phenyl]-2-(diphenylphosphino)benzamide CAS 2750202-75-4 chemical structure

Description

The occurrence of N-[2-[(3aR,8aS)-3a,8a-Dihydro-8H-indeno[1,2-d]oxazol-2-yl]phenyl]-2-(diphenylphosphino)benzamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-[2-[(3aR,8aS)-3a,8a-Dihydro-8H-indeno[1,2-d]oxazol-2-yl]phenyl]-2-(diphenylphosphino)benzamide (CAS 2750202-75-4), molecular formula C35H27N2O2P and molecular weight 538.57 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, N-[2-[(3aR,8aS)-3a,8a-Dihydro-8H-indeno[1,2-d]oxazol-2-yl]phenyl]-2-(diphenylphosphino)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.57 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.
