Solubility
|
In water 3.6 (pH 5), 2.9 (pH 7), 1.9 (pH 9) (all in mg/l, room temperature). In chloroform 94, dimethylformamide 53, acetone 18, xylene 10, ethanol 4, heptane 0.4 (all in g/kg, 25oC).

Stability
|
Hydrolysis DT50 3.5 h (pH 5), 1.5 h (pH 7), <1 h (pH 9) (all 25oC). In some solvents, dissociates to form carbendazim and butyl isocyanate (M. Chiba & E. A. Cherniak, J. Agric. Food Chem., 1978, 26, 573). Solubility in water and stability at various pH values investigated by R. P. Singh & M. Chiba (ibid., 1985, 33, 63). Stable to light. Decomposed on storage in contact with water and under moist conditions in soil. Mechanism of the acid-catalysed decomposition in aqueous media, J. P. Calmon & D. R. Sayag(ibid., 1976, 24, 314, 317).
