Formaldehyde is a flammable, colourless and readily polymerized gas at ambient temperatures. The most common commercially available form is a 30-50% aqueous solution. Formaldehyde is readily soluble in water, alcohols, and ...

Cypermethrin was initially synthesized in 1974 and first marketed in 1977 as a highly active synthetic pyrethroid insecticide, effective against a wide range of pests in agriculture, public health, and animal husbandry. ...

The term polybrominated biphenyls or polybromobiphenyls (PBBs) refers to a group of halogenated hydrocarbons, formed by substituting hydrogen by bromine in biphenyl. PBBs are not known to occur as natural products. They ...

Acetonitrile (CH3CN) is a by-product of acrylonitrile manufacture. It may also be formed by the combustion of wood and vegetation. It is a liquid with an ether-like odour. Acetonitrile is a volatile, highly polar ...

In this monograph, the function and histophysiology of the immune system are reviewed, and the information necessary to understand and interpret the pathological changes caused by immunotoxic insults is provided. Emphasis ...

Pure hexachiorocyclopentadiene (HEX) is a light, lemon-yellow liquid that has a pungent, musty odour. The odour threshold is reported to be 0.0014-0.0016 mg/m3. HEX is highly reactive and volatile at low temperatures. ...

Thallium is a soft and malleable heavy metal with a bluish-white colour. Its relative molecular mass is 204.38. Its most important compound is the colourless, odourless and tasteless thallium(l) sulfate, previously used ...

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 ...

Diflubenzuron is an odourless, white, crystalline solid. It is almost insoluble in water and poorly soluble in apolar organic solvents. In polar to very polar solvents, the solubility is moderate to good, e.g., in acetone ...
