| Hazard Information | Back Directory | [Chemical Properties]
white powder | [Uses]
2-Imidazolidinethione(96-45-7) is a pesticide used in production of fruits and vegetables. It is also used as a new contrast agent for MRI studies based on proton chemical exchange dependent saturation transfe
r. 2-Imidazolidinethione is also a corrosion inhibitor due to the adsorption of the mol. species.
| [Uses]
elastomer accelerator;chlorinated polyethylene (CPE) rubber vulcanizing accelerator agent | [Uses]
Accelerator in synthetic rubber production. | [General Description]
White to pale green crystals or an off-white solid. Odorless when pure, but technical product may have an amine odor. | [Reactivity Profile]
ETHYLENE THIOUREA(96-45-7) may be sensitive to prolonged exposure to light. Incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. May react with acids to liberate hydrogen sulfide. | [Air & Water Reactions]
Slightly soluble in water. | [Hazard]
Questionable carcinogen. | [Potential Exposure]
Ethylene thiourea(96-45-7) is used extensively
as an accelerator in the curing of polychloroprene
(Neoprene) and other elastomers; as a vulcanizing accelerator in rubber processing; in electroplating baths. In addition, exposure to ethylene thiourea also results from the
very widely used ethylene bisdithiocarbamate fungicides.
Ethylene thiourea may be present as a contaminant in the
ethylene bisdithiocarbamate fungicides and can also be
formed when food containing the fungicides is cooked
| [Fire Hazard]
This chemical is combustible. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized
paramedic may consider administering a drug or other
inhalation therapy | [Shipping]

Name Required | [Incompatibilities]
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, epoxides, acid anhydrides, and
acrolein | [Description]

chemical. It has caused contact dermatitis mainly in
rubber workers.
| [Waste Disposal]
Incineration in a furnace
equipped with afterburner and scrubber. | [Definition]
ChEBI: Ethylenethiourea is a member of imidazolidines. | [Health Hazard]
Ethylene thiourea (ETU) is an
antithyroid substance and animal carcinogen. | [Flammability and Explosibility]
Nonflammable | [Carcinogenicity]
Ethylene thiourea is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. | [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, well-ventilated area away from strong oxidizers, acids, acidanhydrides, acrolein. Store in a refrigerator or a cool, dryplace. A regulated, marked area should be establishedwhere this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045. | [Purification Methods]
Crystallise it from EtOH or amyl alcohol. [Beilstein 24 III/IV 22.] | [Toxics Screening Level]
The current initial threshold screening level (ITSL) for ethylene thiourea is 0.28 μg/m3 based on an annual averaging time. |
