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]

[2] Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process.

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. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols. [2]

Methylphosphine is the simplest organophosphorus compound with the formula CH 3 PH 2, often written MePH 2. It is a malodorous gas that condenses to a colorless liquid. It can be produced by methylation of phosphanide salts: [1] KPH 2 + MeI → MePH 2 + KI
The Times story also cited a buprenorphine study by researchers in Sweden that looked at “100 autopsies where buprenorphine had been detected.” According to the Times, the study found that “in two-thirds, it was the direct cause of death, mostly in combination with other drugs.” It was a misreading of the study.
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]
