Methylhexahydrophthalic anhydride is an epoxy hardener, irritant to skin and mucous membranes. It is included in nondiglycidyl-ether-of-bisphenol-A epoxy resins. It can induce both allergic contact dermatitis and immunologic contact urticaria. It is structurally close to methyltetrahydrophthalic anhydride, which can also cause sensitization.

[Description]

Methylhexahydrophthalic anhydride (MHHP A) is an epoxy hardener, irritant to skin and mucus membranes. It is included in non-diglycidyl-ether-of-bisphenol- A epoxy resins. It can induce both allergic contact dermatitis and immunologic contact urticaria. MHHP A is structurally close to methyltetrahydrophthalic anhydride (MTHP A), which can also cause sensitization.
[Uses]

Hexahydro-4-methylphthalic anhydride, mixture of?cis?and?trans may be used as an analytical standard for the determination of the analyte in human biological samples by gas chromatography-mass spectrometry (GC-MS).
[General Description]

Methylhexahydrophthalic anhydride, a congener of phthalic anhydride, is utilized in the production of plastics, paints, and electronic components. It can potentially result in allergenic effects on humans upon exposure and cause immunological reactions.
[Flammability and Explosibility]

Nonflammable
[Synthesis]

5-methyl-3a,4,7,7a-tetrahydroisobenzofuran-1,3-dione could used as a starting material to synthesize Hexahydro-4-methylphthalic anhydride. The byproducts include 5-methylisobenzofuran-1,3-dione, 5-methyl-4,5,6,7-tetrahydroisobenzofuran-1,3-dione, and 6-methyl-3a,4,5,7a-tetrahydroisobenzofuran-1,3-dione.
