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.

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.
