| Hazard Information | Back Directory | [General Description]
Clear yellow liquid. | [Reactivity Profile]
O-CHLOROSTYRENE(2039-87-4) may be sensitive to heat or prolonged exposure to light. This compound may polymerize. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Hazard]
Central nervous system impairment and
peripheral neuropathy. | [Potential Exposure]
In organic synthesis; in the preparation of specialty polymers. | [Fire Hazard]
This compound is combustible. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit | [Shipping]
UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required. | [Incompatibilities]
Contact with elevated temperatures, strong oxidizers, strong bases; or acids may cause fire or explosion. May form peroxides; explosive polymerization may occur. | [Chemical Properties]
clear colourless to light yellow liquid | [Chemical Properties]
o-Chlorostyrene is a flammable, colorless liquid. | [Uses]
2-Chlorostyrene is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff. | [Preparation]
o-Chlorostyrene[2039-87-4] is commercially produced as a monomer from o-chloroethylbenzene by an oxidation technique. p-Chlorostyrene is also produced as a mixture with o-chlorostyrene.
| [Health Hazard]
By analogy to styrene, ochlorostyrene
is expected to cause central
nervous system depression at extremely high
concentrations and possibly irritation of the
eyes, nose, and mucous membranes.
There are no reports of adverse effects in
humans. |
