| Notes: | When this substance is used as an ester or a salt, its identity should be stated, for example TCA-ammonium [7646-88-0], TCA-calcium [21348-16-3], TCA-ethadyl [2514-53-6], TCA-magnesium [16094-02-3], TCA-sodium [650-51-1]. The Weed Science Society of America has approved the name “fenuron-TCA” [4482-55-7] for a mixture with fenuron, and the name “monuron-TCA” [140-41-0] for a mixture with monuron. The name “TCA” was formerly approved by ISO for the sodium salt, but the definition was changed to apply to the acid as part of a rationalisation exercise in 1990. |
