CRIMIDINE Usage And Synthesis

Description

Crimidine is a brown, waxy solid. Molecularweight=171.65; Boiling point=about 145℃; Freezing/Melting point=87℃. Hazard Identification (based onNFPA-704 M Rating System): Health 4, Flammability 1,Reactivity 0. Slightly soluble in water.

Chemical Properties

Crimidine is a brown, waxy solid

Uses

Crimidine can be used for pesticidal utility.

Uses

Rodenticide.

Definition

ChEBI: Crimidine is a member of pyrimidines and an organohalogen compound.

General Description

Brown waxy solid or colorless crystals. Used as a rodenticide. Not registered as a pesticide in the U.S.

Reactivity Profile

CRIMIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

Super toxic; probable oral lethal dose in humans is less than 5 mg/kg or less than 7 drops for a 70 kg (150 lb.) person. May cause serious central nervous system damage leading to convulsions.

Fire Hazard

CRIMIDINE emits highly toxic chloride fumes when heated to decomposition. Avoid acids and acid fumes. Very stable in neutral medium. Avoid decomposing heat.

Potential Exposure

Crimidine is used as a rodenticide. Not registered for use in the United States as a pesticide

First aid

Eye Contact: Immediately remove any contactlenses and flush with large amounts of water for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. Skin Contact: Quickly removecontaminated clothing. Immediately wash area with largeamounts of water. Seek medical attention immediately.Inhalation: Remove the person from exposure, trying toavoid rapid, jerky motions or noise. Begin rescue breathing(using universal precautions, including resuscitation mask)if breathing has stopped and CPR if heart action hasstopped. If seizures occur, begin seizure first aid measures.Call for immediate medical attention to visit the patientprior to transfer if possible. Any facility using this chemicalshould have 24-h rapid access to medical personnel withtraining and equipment for emergency treatment. All areaemployees should be trained in first aid measures forCastrix, including seizure management and CPR.

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with Castrixyou should be trained on its proper handling and storage.Castrix must be stored to avoid contact with strong acids(such as hydrochloric, sulfuric, and nitric) and acid fumes,since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area.

Shipping

UN2588 Pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Acids and acid fumes, strong bases.

Waste Disposal

In accordance with 40CFR165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local 934 Crimidine or federal environmental control agency, or by contacting your regional EPA office.
