sec-Butyl chloroformate Usage And Synthesis

Uses

sec-Butyl Chloroformate-D3 is an intermediate in the synthesis of Picaridin-d3(P436002) which acts on certain olfactory receptor cell types to reduce the activating or attracting effect of odor sources.Insect repellent.

General Description

A colorless liquid. Insoluble in water and more dense than water. Contact may severely irritate skin, eyes, and mucous membranes. Very toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

Air & Water Reactions

Reacts exothermically with moisture in air to generate fumes of hydrochloric acid. Decomposes slowly in water. Insoluble in water.

Reactivity Profile

sec-Butyl chloroformate reacts with water to form sec-butanol, HCl, and CO2. Attacks many metals, especially in humid atmosphere [Handling Chemicals Safely 1980. p. 476]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

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.
