[C][Branch1][Ring1][C][Cl][O][C][C][Cl]"}, {"from": "gpt", "value": "The molecule is a colorless non-flammable liquid with a strong, unpleasant odor. It does not occur naturally, but is manufactured by humans for use in the production of pesticides and other chemicals. Limited amounts of BCEE dissolve in water and also slowly evaporate into air. In the environment, BCEE is broken down by bacteria in soil and water and by chemical reactions in the air, so it does not tend to persist for long periods. (L183)"}]
