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.
Schedule 2 substances, in the sense of the Chemical Weapons Convention, are chemicals that are feasible to use as chemical weapons themselves (Part A), or their manufacturing precursors (Part B), and which have small-scale applications outside of chemical warfare and so can be legitimately manufactured in small quantities.
Dimethyl methylphosphonate (DMMP), one of the simplest phosphonate diesters; Etidronic acid (HEDP): 1-hydroxyethylidene-1,1-diphosphonic acid, used in detergents, water treatment, cosmetics and pharmaceuticals; ATMP: Aminotris(methylenephosphonic acid), chelating agent; EDTMP: Ethylenediaminetetra(methylenephosphonic acid), chelating agent
Methylphosphonyl dichloride is produced by oxidation of methyldichlorophosphine, with sulfuryl chloride: [3]. CH 3 PCl 2 + SO 2 Cl 2 → CH 3 P(O)Cl 2 + SOCl 2. It can also be produced from a range of methylphosphonates (e.g. dimethyl methylphosphonate) via chlorination with thionyl chloride.
Dimethylphosphite is an organophosphorus compound with the formula (CH 3 O) 2 P(O)H, known as dimethyl hydrogen phosphite (DMHP). Dimethylphosphite, is a minor tautomer of the phosphorus(V) derivative. It is a reagent for generating other organophosphorus compounds, exploiting the high reactivity of the P-H bond. The molecule is tetrahedral. It ...
Methylphosphinic acid is a monobasic acid, the simplest of the phosphinic acids.A central phosphorus atom is connected to a hydroxy group, a hydrogen atom, a methyl group 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.
