Use：: Dimethyl Phosphite（DMP）is used as a reagent in the synthesis of 4-(thiophen-2-ylmethyl)-2H-phthalazin-1-ones as potent PARP-1 inhibitors. It is also used as a reagent in the synthesis of estafiatin phosphonate derivatives which exhibit antibacterial and antifungal activity. Dimethyl Phosphite is a degradation product of the pesticides trichlorphon and malathion and may be released into the envionment following their application. It is a contaminant (approxiately 2%) in the chemical intermediate triethyl phosphite, which hydrolyses readily to dimethyl hydrogen phosphite in the presence of moist air or water. Dimethyl Phosphite is used as a flame retardant on Nylon 6 fibres and, in combination with guanidine and formaldehyde, to impart flame and crease resistance to cotton textiles. The compound is also used to increase fire resistance to cellulosic textiles, acrolein-grafted polyamide fibres and y-irdiated polyethylene. lt is used as a lubricant additive, as a chemical intermediate in the production of organophosphorous pesticides and as an adhesive. Dimethyl Phosphite has also been used as a stabilizer in oil and plaster and, in combination with pyroctechol, as a corrosion inhibitor on steel.
