General description

Bis(7-methyloctyl) phthalate, also known as DiNP, is a high molecular weight phthalate used predominantly as a plasticizer for polyvinyl chloride (PVC) articles in the production of hoses, shoe soles, wire and cable, soft vinyl toys and flooring.

Application

Bis(7-methyloctyl) phthalate (DiNP) may be used as an analytical standard for the determination of the analyte in human urine, sediments and paper cups by chromatography techniques.

Di-iso-nonylphthalate (DINP), a complex mixture of predominantly nine-carbon branched chain dialkyl phthalate isomers, has replaced di-(2-ethylhexyl)phthalate (DEHP) as the major plasticiser for polyvinylchloride (PVC) polymers. Similar to DEHP, DINP is a developmental and reproductive toxicant in rodents. This study for
