131-70-4 - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | dibutyl phthalate (DBP) is a kind of phthalate esters (PAEs) and is widely used in plastic processing industry as a plasticizer. Monobutyl phthalate (MBP) is a degradation product and synthetic intermediate of DBP. |
| application | can be used to synthesize cytarabine derivative 5. Cytarabine is an analog of cytosine nucleoside, an inhibitor of DNA polymerase. It can prevent DNA synthesis, can also be incorporated into DNA, interfere with DNA replication, and can also block the reduction of cytosine nucleotides to deoxycytosine nucleotides. |
| biological activity | Monobutyl phthalate is the main metabolite of dibutyl phthalate (DBP) and has anti-androgen effect. Monobutyl phthalate is an embryonic poison. |
