Methylpyrazolyl diethylphosphate (CAS NO.108-34-9) is also called 3-Methylpyrazolyl-5-diethylphosphate ; AI3-24723 ; Diethyl 3-methyl-5-pyrazolyl phosphate ; ENT 24,723 ; G-24483 ; Geigy G-24483 ; O,O-Diaethyl-O-(3-methyl-1H-pyrazol-5-yl)-phosphat [German] ; O,O-Diethyl O-(3-methyl-5-pyrazolyl) phosphate ; O,O-Diethyl-O-(3-methyl-1H-pyrazol-5-yl)-fosfaat [Dutch] ; O,O-Dietil-O-(3-metil-1H-pirazol-5-il)-fosfato [Italian] ; Phosphate de diethyle et de 3-methyl-5-pyrazolyle ; Phosphate de diethyle et de 3-methyl-5-pyrazolyle [French] ; Phosphoric acid, diethyl-(3-methyl-5-pyrazolyl) ester ; Phosphoric acid, diethyl-, 3-methylpyrazole-5-yl ester ; Pirazoxon ; Pyrazol-3(or 5)-ol, 5(or 3)-methyl-, diethyl phosphate ; Pyrazoxon ; Pyrazoxone . Methylpyrazolyl diethylphosphate (CAS NO.108-34-9) is high toxic. It is flammable by fire. It will produce toxic nitrogen oxide, phosphorus oxide gas by heat. So the storage environment should be ventilate, low-temperature and dry. Keep Methylpyrazolyl diethylphosphate (CAS NO.108-34-9) separate from raw materials of food.
