In some countries, there are additional uses in rice, sugar cane, cereals and oilseed rape.

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 2.6 d (25^οC).
