Ethyl 5-(4-chlorophenyl)-4,6-dioxo-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,4-d]isoxazole-3-carboxylate CAS 338792-98-6

Description

The occurrence of Ethyl 5-(4-chlorophenyl)-4,6-dioxo-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,4-d]isoxazole-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-(4-chlorophenyl)-4,6-dioxo-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,4-d]isoxazole-3-carboxylate (CAS 338792-98-6) is a high-purity analytical reference standard with the molecular formula C14H11ClN2O5 and a molecular weight of 322.70 g/mol.

Structurally, Ethyl 5-(4-chlorophenyl)-4,6-dioxo-3a,5,6,6a-tetrahydro-4H-pyrrolo[3,4-d]isoxazole-3-carboxylate (C14H11ClN2O5) contains a nitrogen-containing heterocyclic scaffold, 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 322.70 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
