Chemical name: 4-amino-3,5,6-trichloropyridine-2-carboxylic acid or 4-amino-3,5,6-trichloropicolinic acid
CAS no.: 1918-02-1

Structural formula:

Molecular formula: C₆H₃Cl₃N₂O₂
Physical & chemical property:
Physical State: Colourless powder, with a chlorine-like odour.
Melting point: Decomposes at c. 215°C without melting
Solubility: in water 430mg/l (25°C), In acetone 19.8, ethanol 10.5, isopropanol 5.5, acetonitrile 1.6, diethyl ether 1.2, dichloromethane 0.6, benzene 0.2 (all in g/l, 25°C)
Stability: Very stable to acids and alkalis, but decomposed by hot concentrated alkalis. Readily forms water-soluble alkali-metal and amine salts. In aqueous solution, decomposed by u.v. irradiation, DT50 2.6d (25°C).
Specification: 93%TC
Uses: Selective contact herbicide, absorbed rapidly by the roots and leaves, and translocated both acropetally and basipetally, accumulating in new growth. 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 installation, roads, railways, airports, under powerlines and along pipeline. In some countries, there are additional uses in rice, sugar cane, cereals and oilseed rape.
