    Specification :

    A volatile organophosphorus insecticide. It is of high
    acute toxicity but its rapid metabolism renders it safe under
    correct conditions of use. It is directly active without having
    to be metabolized first.

    SELECTED PROPERTIES

    Physical characteristics - When pure a colourless liquid, b.p.
    35°C at 0.05 Torr, density 1.415 at 25°C. Corrosive to mild
    steel and other metals.

    Solubility - Water at 20°C, 0.9%, kerosine 2-3%. Miscible with
    aromatic hydrocarbon solvents, chlorinated hydrocarbon solvents
    and alcohols.

    Stability - Stable to heat, hydrolyses in aqueous solutions. The
    saturated aqueous solution is decomposed at the rate of 3% per
    day (half life 23 days). Decomposition occurs more rapidly in
    alkali and in strongly acid solutions. At pH 1 complete
    hydrolysis occurs within 50 minutes at room temperature. The
    vapour is rapidly hydrolysed in air. Compatible with most
    technical pesticides.
