Isobutyl isocyanate Chemical Properties,Uses,Production
Uses
Isobutyl Isocyanate, is an building block that cna be used for the synthesis of Boceprevir (B674500), a novel, potent, selective, orally bioavailable NS3 protease inhibitor used for the treatment of Hepatitis C virus (HCV) infection.
General Description
A colorless liquid. Flash point near 40°F. Less dense than water. Contact may severely irritate skin, eyes and mucous membranes. May be very toxic by ingestion, inhalation and skin absorption. Used to make pesticides and pharmaceuticals.
Air & Water Reactions
Highly flammable. Soluble in water.
Reactivity Profile
Isocyanates and thioisocyanates, such as Isobutyl isocyanate, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)].
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
