Trichlorfon is a colourless crystalline powder that is stable at room temperature. It is slowly hydrolysed in acid media; the half-life is 526 days at pH 1-5 and 20°C. In alkaline media, at pH 8 and 37.5 °C, it hydrolyses ...

Aldicarb has a slight sulfur smell. It has a melting point of 100 °C and a specific gravity of 1.195 at 25 °C. it is soluble in water, sensitive to heat, and relatively unstable. Analytical methods for aldicarb include ...

Isobenzan is a whitish to light-brown crystalline powder, with a mild chemical odour. It is relatively stable to acids, but liable to dehydrochlorination under strongly alkaline conditions. Solubility in organic solvents: ...

Methomyl is a white crystalline solid with a melting point of 77 °C. It is soluble in water and in many organic solvents. It is stable at temperatures up to 140 °C; the autoignition temperature is 265 °C. Methomyl is stable ...

Bromadiolone is a white to off-white powder. Its solubility in water is very low (less than 20 mg/litre at 20 °C). It is slightly soluble in ethanol and ethyl acetate, and soluble in dimethylformamide. The flash-point ...

Ammonia is a colourless acrid-smelling gas at room temperature and normal atmospheric pressure. Most people can identify its odour at 35 mg/rn3 in air. It can be stored and transported as a liquid at a pressure of 10 ...

Barium is an alkaline earth metal that occurs in nature in a combined form. It is present in rocks, minerals, soils, air, natural waters, and fossil fuels. Some barium salts (e.g., acetate, nitrate, and chloride) are quite ...

Commercial 1,3-dichioropropene is a mixture of cis- and trans- isomers and 92% pure. It may also be used in admixtures with 1 ,2-dibromoethane (Dorloe) or with 1 ,2dichloropropane (D-D , soil fumigant; Nemex Telone , and ...

Pure methyl parathion is crystalline and white. It is relatively insoluble in water, poorly soluble in petroleum ether and mineral oils, and readily soluble in most organic solvents. Methyl parathion is stable at pH 1-7, ...

The PCBs are chlorinated hydrocarbons that are manufactured commercially by the progressive chlorination of biphenyl in the presence of a suitable catalyst (e.g., iron chloride). Depending on the reaction conditions, the ...
