Chlormequat chloride Chemical Properties, Uses, Production
Description
Chlormequat chloride is a white to yellowishcrystalline solid with a fish-like odor. Molecularweight=158.1; Freezing/Melting point=245℃ (decomposes); Hazard Identification (based on NFPA 704 M RatingSystem): Health 3, Flammability 0, Reactivity 0. Highly soluble in water. Carrier solvents used in commercial productsmay alter physical and toxicological properties.
Chemical Properties
Chlormequat chloride is a white to yellowish crystalline solid with a fish-like odor.
Chemical Properties
white or light yellow crystals
Uses
Chlorocholine Chloride is a plant growth regulator that is primarily used on ornamental plants.
Uses
Plant growth regulator on ornamental plants.
Definition
A phytocidal bipyridilium quaternary ammonium salt.
Production Methods
Chlormequat chloride is produced through a straightforward chemical synthesis involving two key reactants: ethylene dichloride and trimethylamine. Ethylene dichloride is typically heated in a reactor and trimethylamine is introduced either in liquid or gaseous form. This reaction produces chlormequat chloride via quaternization of the amine.
General Description
White crystals with a fishlike odor. Used as a plant growth regulator. Said to be effective for cereal grains, tomatoes, and peppers.
Air & Water Reactions
Very hygroscopic. Water soluble. Aqueous solutions are acidic.
Reactivity Profile
Chlormequat chloride is incompatible with strong oxidizing agents. Chlormequat chloride is corrosive to unprotected metals.
Hazard
Toxic; corrosive.
Health Hazard
Inhalation of spray and prolonged or repeated contact with skin should be avoided.
Fire Hazard
Flash point data for Chlormequat chloride are not available; however, Chlormequat chloride is probably combustible.
Agricultural Uses
Plant growth regulator: Said to be effective for cereal grains, tomatoes, and peppers; cotton, grapes, mango, tobacco, vegetables. In California, major uses are in greenhouse plants and flowers and in nurseries, including geraniums, azaleas, hibiscus.

Biochem/physiol Actions
Chlormequat (Chlorocholine) chloride is a synthetic plant growth regulator that inhibits gibberellin (GA) biosynthesis. It is used to study the mechanisms and effects of gibberellins on plant cell growth and differentiation.
Mechanism of action
Gibberellin biosynthesis inhibitor - reducing cell elongation
Safety Profile
Human poison by ingestion and intravenous routes. Moderately toxic by skin contact. Human systemic effects: respiratory depression. Questionable carcinogen with experimental neoplastigenic data. Mutation data reported.
Potential Exposure
People engaged in the manufacture, formulation, and application of this plant growth regulator said to be effective for cereal grains, tomatoes, and peppers.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit. Medical observation isrecommended for 24-48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonaryedema, a doctor or authorized paramedic may consideradministering a corticosteroid spray.
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with chlormequat chloride you should be trained on its proper handlingand storage. Keep away from strong oxidizers. Store in acool, dry place and protect from heat and moisture. Sourcesof ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in amanner that could create a potential fire or explosionhazard.
Shipping
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Incompatibilities
Chlormequat chloride decomposes on heating or in fire forming nitrogen oxides, carbon monoxide, and hydrogen chloride fumes. This chemical decomposes on heating with strong aqueous alkali solutions forming trimethylamine and other gaseous products. Contact with strong oxidizers may cause fire and explosions. Attacks many metals in presence of water.
Waste Disposal
Incinerate in a unit with effluent gas scrubbing.
