Description
Solid; [Merck Index] White powder; [Sigma-Aldrich MSDS]
Sources/Uses
Used as an intermediate for resins, plasticizers, dyes, inks, and adhesives; [Merck Index] Used strictly to make trimellitic anhydride; [OECD SIDS: Trimellitic Anhydride and Trimellitic Acid - 2002]
Comments
Trimellitic anhydride demonstrates no evidence of teratogenicity or fetotoxicity in experimental animals; A mild skin and severe eye irritant; Structural analog of trimellitic anhydride (TMA); TMA rapidly forms trimellitic acid in aqueous environments and in conditions used to test its toxicity; Although similar in systemic toxicity, trimellitic does not share the sensitization potential of TMA; [OECD SIDS: Trimellitic Anhydride and Trimellitic Acid - 2002] A skin and strong eye irritant; [Sigma-Aldrich MSDS] See "Trimellitic anhydride." See "Trimethyl 1,2,4-benzenetricarboxylate."
