    Mol. wt. 241.5 

    M.f. C6H3Cl3N2O2 

    Form Light brown solid, with a chlorine-like odour. 

    M.p. Decomposes at c. 190 ºC before melting 

    V.p. 8×10-11 mPa (25 °C) 

    KOW logP = 1.9 (20 °C, 0.1N HCl, i.e. neutral species) 

    S.g./density Bulk density 0.895 (25 °C)  

    Solubility In water 0.056 g/100 ml (20 °C); pH of saturated water solution 3.0 (24.5 °C). In hexane <0.004, toluene 0.013, acetone 1.82, methanol 2.32 (all in g/100 ml, 20 °C)..

    APPLICATIONGS
    Growth regulator. Synthetic auxin mimic (acting like indolylacetic acid). Biochemistry
    Selective systemic herbicide, absorbed rapidly by the roots and leaves, and translocated both acropetally and basipetally, accumulating in new growth. Mode of action
    The main use of picloram salts and esters is for the management of unwanted vegetation in rangeland, grass pastures, forestry, as well as non-crop land and rights-of-way sites such as around industrial and military installations, roads, railways, airports, under powerlines and along pipelines. In some countries, there are additional uses in rice, sugar cane, cereals and oilseed rape. Uses
