• 1,2-Benzenedicarboxylic acid, 1-butyl 2-cyclohexyl ester: ACTIVE
• Phthalate esters are first hydrolyzed to their monoester derivative. Once formed, the monoester derivative can be further hydrolyzed in vivo to phthalic acid or conjugated to glucuronide, both of which can then be excreted. The terminal or next-to-last carbon atom in the monoester can also be oxidized to an alcohol, which can be excreted as is or first oxidized to an aldehyde, ketone, or carboxylic acid. The monoester and oxidative metabolites are excreted in the urine and faeces. (A2884)
