4-Methylhexahydro-4,7-epoxyisobenzofuran-1,3-dione CAS 6345-56-8

Description

The occurrence of 4-Methylhexahydro-4,7-epoxyisobenzofuran-1,3-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methylhexahydro-4,7-epoxyisobenzofuran-1,3-dione (CAS 6345-56-8), molecular formula C9H10O4 and molecular weight 182.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methylhexahydro-4,7-epoxyisobenzofuran-1,3-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
