Any of a class of derivatives of fluorine-9-carboxylicacids that powerfully regulate plant growth anddevelopment. They inhibit shoot elongation andcause morphological abnormalities in intact plants.They also promote the visions that give rise to lat-eral primordial in the root pericycle. | [Melting point ]

| Hazard Information | Back Directory | [Description]
Chlorfluenol-methyl is an obsolete herbicide and plant growth regulator. It has a low aqueous solubility and is non-volatile. It is not expected to be persistent in the environment. Whilst limited, data that is available suggests a low to moderate toxicity to biodiversity. Chlorflurenol-methyl has a low mammalian oral toxicity. | [Chemical Properties]
Plasticin Plasticin is insoluble in water, soluble in ethanol and so on. It is sensitive to UV photolysis, especially its free acid and amide salts, and is unstable to heat. Non-toxic, the final decomposition product is carbon dioxide, no pollution to the environment, not a long-lasting inhibitor. | [Uses]
Chlorflurenol-methyl is an auxin polar transport inhibitor that effects elongation growth of the excised fourth internode of tulips. Chlorflurenol-methyl is a pesticide. | [Production Methods]
Chlorflurenol-methyl is commercially produced by esterifying chlorflurenol, a hydroxyfluorene carboxylic acid derivative, with methanol under acidic conditions. This reaction yields methyl 2-chloro-9-hydroxyfluorene-9-carboxylate, the active compound. The process involves standard esterification techniques, followed by purification steps such as recrystallisation or distillation to achieve high purity. | [Mechanism of action]
Absorbed by leaves and roots, Auxin inhibitor | [Pesticide Type]
