Chemical Structure
Description
Ethyl (R)-2-(7-fluoro-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate (CAS 1850385-84-0), molecular formula C12H14FNO3 and molecular weight 239.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl (R)-2-(7-fluoro-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate (C12H14FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 239.24 g/mol, it falls into the medium-molecular-weight range. 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.
