5220-39-3 11H-Cyclohepta(b)quinolin-11-one, 5,6,7,8,9,10-hexahydro- 5-21-08-00522 (Beilstein Handbook Reference) BRN 1529222 5,6,7,8,9,10-Hexahydro-11H-cyclohepta(b)quinolin-11-one 7,8,9,10-Tetrahydro-6H-cyclohepta(b)quinolin-11-one (CAS 5220-39-3) is a high-purity analytical reference standard with the molecular formula C14H15NO and a molecular weight of 213.28 g/mol.
Structurally, 5220-39-3 11H-Cyclohepta(b)quinolin-11-one, 5,6,7,8,9,10-hexahydro- 5-21-08-00522 (Beilstein Handbook Reference) BRN 1529222 5,6,7,8,9,10-Hexahydro-11H-cyclohepta(b)quinolin-11-one 7,8,9,10-Tetrahydro-6H-cyclohepta(b)quinolin-11-one (C14H15NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 213.28 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
