 Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate (CAS NO.119-38-0) is also called (1-Isopropil-3-metil-1H-pirazol-5-il)-N,N-dimetil-carbammato ; 1-Isopropyl-3-methyl-5-pyrazolylester kyseliny dimethylkarbaminove ; 1-Isopropyl-3-methylpyrazolyl-(5)-dimethylcarbamate ; 5-23-10-00529 (Beilstein Handbook Reference) ; 5-Methyl-2-isopropyl-3-pyrazolyl dimethylcarbamate ; AI3-19060 ; BRN 0201858 ; Carbamic acid, dimethyl-, 1-isopropyl-3-methylpyrazol-5-yl ester ; Dimethyl-5-(L-isopropyl-3-methyl-pyrazolyl)-carbamate ; Dimethylcarbamic acid 3-methyl-1-(1-methylethyl)-1H-pyrazol-5-yl ester ; ENT 19,060 ; EPA Pesticide Chemical Code 511500 ; G 23611 ; Geigy G-23611 ; HSDB 31 ; Isolan (pesticide) ; Primin ; Pyrazol-5-ol, 1-isopropyl-3-methyl-, dimethylcarbamate ; Saolan . Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate (CAS NO.119-38-0) is colorless liquid. Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate (CAS NO.119-38-0) is classified as extremely toxic. Probable oral lethal dose in humans is 5-50 mg/kg or between 7 drops and 1 teaspoonful for a 150-lb. person. A cholinesterase inhibitor; although it is not an organic phosphate, it resembles that group in action. When heated to decomposition, Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate (CAS NO.119-38-0) emits toxic fumes of nitrogen oxides. So the storage environment should be ventilate, low-temperature and dry. Keep Dimethyl-5-(1-isopropyl-3-methyl-pyrazolyl)carbamate (CAS NO.119-38-0) separate from raw materials of food.
