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]
Methyldichlorophosphine is produced by alkylation of phosphorus trichloride with methyl iodide followed by reduction of the resulting phosphonium salt with iron powder: [2] [3]
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 .
About two months ago, The Quaker Oats Company voluntarily recalled pancake and waffle mix from its brand Pearl Milling Company. The January recall has now been officially categorized by the U.S ...
THPC can be synthesized with high yield by treating phosphine with formaldehyde in the presence of hydrochloric acid. [1]PH 3 + 4 H 2 C=O + HCl → [P(CH 2 OH) 4]Cl. The cation P(CH 2 OH) 4 + features four-coordinate phosphorus, as is typical for phosphonium salts.
