Reactivity
CYHEXATIN is incompatible with strong oxidizing agents. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Stable in aqueous suspensions in neutral and alkaline pH (above pH 6), but reacts exothermically as a base in the presence of strong acids to form salts. Converts to dicyclohexyltin oxide and further to cyclohexylstannoic acid upon exposure to ultraviolet radiation.
