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. [3] It can be used as a sarin-simulant for the calibration of organophosphorus detectors.
Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glyphosate (the active molecule of the herbicide Roundup ), and ethephon , a widely used plant growth regulator.
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.
Methylphosphonyl difluoride is both reactive and corrosive. It is absorbed through skin and causes burns and mild nerve agent symptoms. It reacts with water, producing HF fumes and methylphosphonic acid as a result. It is also capable of corroding glass.
Tetrakis(hydroxymethyl)phosphonium chloride (THPC) is an organophosphorus compound with the chemical formula [P(CH 2 OH) 4]Cl. It is a white water-soluble salt with applications as a precursor to fire-retardant materials [ 1 ] and as a microbiocide in commercial and industrial water systems.
Dichlorobis(triphenylphosphine)nickel(II) refers to a pair of metal phosphine complexes with the formula NiCl 2 [P(C 6 H 5) 3] 2. The compound exists as two isomers, a paramagnetic dark blue solid and a diamagnetic red solid. These complexes function as catalysts for organic synthesis. [1]
