Useful:

Canonical SMILES:CC1CCC2C(C1)C(=O)OC2=O
Inhalation Risk:A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20 °C; on spraying or dispersing, however, much faster.
Effects of Short Term Exposure:The substance is irritating to the eyes, skin and respiratory tract.
Effects of Long Term Exposure:Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.
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).
