| Hazard Information | Back Directory | [Description]
Chlorphonium chloride is an obsolete plant growth regulator that was used largely on ornamentals. It has a high aqueous solubility but is non-volatile. It can be very persistent in soil systems. Little data is available regarding its toxicity to biodiversity. It has a moderate mammalian toxicity and is a skin and eye irritant. | [Chemical Properties]
White, crystalline solid; mild aromatic
odor. Technical grade melts at 114–120C. Soluble
in water, acetone, ethanol, isopropanol and hot benzene;
insoluble in hexane and ether. | [Definition]
ChEBI: Chlorphonium chloride is an organic molecular entity. | [Production Methods]
Chlorphonium chloride is commercially produced in a process that involves the quaternization of tributylphosphine with 2,4-dichlorobenzyl chloride under controlled conditions, typically in an inert solvent like toluene or acetonitrile. The reaction yields the phosphonium salt, which is then purified through crystallisation or solvent extraction. | [Mechanism of action]
Systemic. Gibberellin biosynthesis inhibitor | [Pesticide Type]
Herbicide; Plant Growth Regulator |
