Monobenzyl phthalate (MBzP) also known as benzene-1, 2-dicarboxylic acid is an organic compound with the condensed structural formula C6H5CH2OOCC6H4COOH. It is the major metabolite of butyl benzyl phthalate(BBP), a common plasticizer.[2]BBP can also be metabolized into monobutyl phthalate (MBP).[3][4] Like many phthalates, BBP has attracted attention as a potential endocrine disruptor.[5][6][7]
