Hazard Information | Back Directory | [General Description]
A clear colorless liquid. Burns, though may be difficult to ignite. Corrosive to tissue. Denser than water and insoluble in water. Vapors heavier than air. Used to make other chemicals. | [Reactivity Profile]
Halogenated unsaturated aliphatic compounds, such as 1,4-DICHLORO-2-BUTENE(764-41-0), are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. | [Air & Water Reactions]
Highly flammable. Reacts slowly with water to form hydrochloric acid. Insoluble in water. | [Health Hazard]
Inhalation of vapor irritates nose and throat. Contact with eyes causes intense irritation and tears. Contact of liquid with skin causes severe blistering and dermatitis. Ingestion causes severe irritation of mouth and stomach. | [Potential Exposure]
DC occurs as a by-product in chloroprene manufacture and may be used as a chemical
intermediate | [Fire Hazard]
Special Hazards of Combustion Products: Decomposition vapors contain phosgene and hydrogen chloride gases; both are toxic and irritating. | [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. If victim is conscious, administer water
or milk. Do not induce vomiting. | [Shipping]

o.s. with an LC50 ≦ 1000 ml/m3 and saturated vapor
concentration ≧to 10 LC50, Hazard class: 6.1; Labels:
6.1-Poisonous materials, 3-Flammable liquid, Technical Name
Required, Inhalation Hazard Zone B. UN2920 Corrosive
liquids, flammable, n.o.s., Hazard class: 8; Labels: 8-Corrosive
material, 3-Flammable liquid. The code “D” identifies proper
shipping names which are appropriate for
describing materials for domestic transportation but may be
inappropriate for international transportation under the provisions of international regulations, e.g., IMO, ICAO). An alternate proper shipping name may be selected when either
domestic or international transportation is involved | [Incompatibilities]
Vapors may form explosive mixture
with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away
from alkaline materials, strong bases, strong acids, oxoacids,
and epoxides. (cis-isomer): Reacts slowly with water forming hydrogen chloride. Attacks metals and may form other,
more dangerous materials; attacks some plastics. | [Description]

Explosivelimits: LEL = 1.5%; UEL = 4.0%. Reacts slowly withwater.(trans-isomer): This material has a sweet, pungent odor.Boiling point = 155.5℃; Freezing/Melting point 5 1-3℃;Flash point = 53℃. The explosive limits for the trans-isomer are LEL = 1.5%; UEL = 4%. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 2, Reactivity 0. Insoluble in water. The transisomer, only, appears on the EHS list. | [Chemical Properties]
The 1,4-dichloro-2-butenes are colorless
liquids. Some have a distinct odor. (cis-isomer) | [Waste Disposal]
High-temperature incineration
with hydrochloric acid scrubbing. Consult with environmental regulatory agencies for guidance on
acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with
EPA regulations governing storage, transportation, treatment, and waste disposal. | [Uses]
1,?4-?Dichloro-?2-?butene is an organic reagent used in the preparation of heterocyclic compounds. Used in the synthesis of γ-turn peptidomimetic scaffold neuroprotectives as a JNK3 allosteric ligand.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list. | [Definition]
ChEBI: Trans-1,4-Dichlorobutene is an organochlorine compound. | [Chemical Reactivity]
Reactivity with Water Reacts slowly to form hydrochloric acid; Reactivity with Common Materials: Corrodes metal when wet; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | [storage]
(1) Color Code—Red (cis-isomer): FlammabilityHazard: Store in a flammable liquid storage area orapproved cabinet away from ignition sources and corrosiveand reactive materials. (2) Color Code—White: Corrosiveor Contact Hazard; Store separately in a corrosion-resistantlocation. Prior to working with this chemical you should betrained on its proper handling and storage. Before enteringconfined space where this chemical may be present, checkto make sure that an explosive concentration does not exist.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Where possible, automaticallypump liquid from drums or other storage containers to process containers. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045. |
