Description and Uses
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.
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).
