Diisopropyl methylphosphonate (DIMP), also known as diisopropyl methane-phosphonate and phosphonic acid and methyl-bis-(1-methylethyl)ester, is a chemical by-product in the production of sarin gas when two equivalents of isopropyl alcohol react with methylphosphonyl difluoride instead of one.{{cite web|url=https://wwwn.cdc.gov/TSP/substances/ToxSubstance.aspx?toxid=203 |title=ATSDR - Toxic Substances - Diisopropyl Methylphosphonate (DIMP) |publisher=Atsdr.cdc.gov }}

DIMP is a colorless liquid that has been shown to affect the hematological (blood forming) system in animals.{{cite web|url=http://www.atsdr.cdc.gov/toxfaqs/tfacts119.pdf |title=diisopropyl methylphosphonate datasheet |publisher=ATSDR |id=tf119 |date=August 1999 |access-date=2012-10-18}} Its chemical formula is {{chem2|C7H17O3P}}.{{cite web|url=http://www.chemicals.pl/ |title=Center of Chemicals|publisher=Chemicals.pl |date= |access-date=2012-10-18}}

It degrades into isopropyl methylphosphonic acid.
