  1-Bromobutane with CAS number of 109-65-9 is also called for N-butyl bromide ; Butyl bromide ; 1-Bromobutane ; 1-Brombutan ; 1-Bromo-butan ; 1-butylbromide ; Bromo butane ; Butane,1-bromo- . Use with adequate ventilation. Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Take precautionary measures against static discharges. Avoid ingestion and inhalation. Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Flammables-area. 1-Bromobutane (CH₃(CH₂)₂CH₂Br) that is insoluble in water, but soluble in ethanol and diethyl ether. As a primary alkyl halide, it is especially prone to SN2 type reactions. It is commonly used as an alkylating agent, or in combination with magnesium metal in dry ether (Grignard reagent) to form carbon-carbon bonds. 1-Bromobutane may also be used to form other organometallic compounds.
