Analytically difficult to grasp

Di-(2-propylheptyl)phthalate (DPHP) is used as plasticizer, especially in polymers like PVC. Due to analytical difficulties within a total phthalate determination, DPHP is analysed with a specific method.

The Environmental Specimen Bank do not analyses the parent substance DPHP in human samples, but its main metabolites.

Substances

cx-MPHxP Mono(propyl-6-carboxyhexyl) phthalate is a secondary metabolite of DPHP.
OH-MPHP Mono(propyl-6-hydroxyheptyl) phthalate is a secondary metabolite of DPHP.
Oxo-MPHP Mono(propyl-6-oxo-heptyl) phthalate is a secondary metabolite of DPHP.
