Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 9-Chloro-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
9-Chloro-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one (CAS 1310699-69-4), molecular formula C10H10ClNO and molecular weight 195.65 g/mol, is a CATO reference standard with documented purity and traceability.
