Description
3,3-Dimethyl 5-(2,4-dichlorophenyl)-4,6-dioxo-hexahydro-2H-pyrrolo[3,4-d][1,2]oxazole-3,3-dicarboxylate (CAS 339011-66-4), molecular formula C15H12Cl2N2O7 and molecular weight 403.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3-Dimethyl 5-(2,4-dichlorophenyl)-4,6-dioxo-hexahydro-2H-pyrrolo[3,4-d][1,2]oxazole-3,3-dicarboxylate (C15H12Cl2N2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 403.17 g/mol, it falls into the moderately-high-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.
