Chemical Structure

4-Methoxyisoindolin-1-one CAS 366453-22-7 chemical structure

Description

The occurrence of 4-Methoxyisoindolin-1-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methoxyisoindolin-1-one (CAS 366453-22-7), molecular formula C9H9NO2 and molecular weight 163.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methoxyisoindolin-1-one (C9H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 163.17 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).

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.

As a certified reference material (CRM), 4-Methoxyisoindolin-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
