Methylphosphonyl dichloride (DC) or dichloro is an organophosphorus compound. It has commercial application in oligonucleotide synthesis, [1] but is most notable as being a precursor to several chemical weapons agents. It is a white crystalline solid that melts slightly above room temperature. [2]
116.91 g·mol −1 Appearance ... SW and methylphosphonous dichloride) is an organophosphorus compound with the chemical formula CH 3 PCl 2. It is a colorless ...
Dimethyl methylphosphonate can be prepared from trimethyl phosphite and a halomethane (e.g. iodomethane) via the Michaelis–Arbuzov reaction. [2]Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons.
Methylphosphonic acid is an organophosphorus compound with the chemical formula CH 3 P(O)(OH) 2.The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen.
Methylphosphonyl difluoride (DF), also known as EA-1251 [2] or difluoro, [3] is a chemical weapon precursor. Its chemical formula is CH 3 POF 2 . It is a Schedule 1 substance under the Chemical Weapons Convention .
It, along with methylphosphonyl difluoride (DF), was developed during the 1980s in order to replace an aging stockpile of unitary chemical weapons. [3] QL is listed as a Schedule 1 chemical by the Chemical Weapons Convention .
GV is a part of a series of nerve agents with properties similar to the "G-series" and "V-series". It is a potent acetylcholinesterase inhibitor with properties similar to other nerve agents, being a highly poisonous vapour. Treatment for poisoning with GV involves drugs such as atropine, benactyzine, obidoxime, and HI-6. [1] [2]
[1] [2] However, aluminum chloride often induces diarylation; a cleaner catalyst for monoarylation is stannic chloride. [2] The compound is an intermediate for the synthesis of other chemicals for instance dimethylphenylphosphine: C 6 H 5 PCl 2 + 2 CH 3 MgI → C 6 H 5 P(CH 3) 2 + 2 MgICl. Many tertiary phosphines can be prepared by this route. [3]
