Bromoxynil octanoate in the environment has a half-life of about 10 days, and breaks down into harmless compounds.^[2] It breaks down much quicker than bromoxynil, ioxynil or chloroxynil, which all last about a month in aerobic soil.^[3]

Bromoxynil octanoate acts by inhibiting photosynthesis at photosystem II, destroying cells, making it a Group C, (Aus), Group C3, (Global), or Group 6 (numeric) under the HRAC system. Weeds show symptoms after four to seven days of chlorotic leaves and desiccation.^[4][5]

It has been sold under the trademarks Bromoxynil, Broclean, Bromox, Brominex, Bromolex, Bromolex and Bromoxymobeed.
