clear colourless liquid
Uses
Different sources of media describe the Uses of 107-82-4 differently. You can refer to the following data:
1. An alkyl halide and organic synthesis reagent.
2. In organic synthesis.
3. 1-Bromo-3-methylbutane was used in the synthesis of 1-(3-methylbutyl)pyrrole and in the production of pentyl peroxy radical by direct photolysis production method. It was also used as extraction solvent for determination of polycyclic aromatic hydrocarbons in water samples using liquid-liquid microextraction combined with gas chromatography-mass spectrometry. It is also used as an alkyl halide and organic synthesis reagent.

General Description
A colorless liquid. Flash point 21°F. Slightly soluble in water and denser than water. Vapors are heavier than air.
Air & Water Reactions
Highly flammable. Slightly soluble in water and denser than water.
Reactivity Profile
Halogenated aliphatic compounds, such as 1-Bromo-3-methylbutane, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Gives toxic fumes of bromine when burned.
Health Hazard
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Moderately toxic by
intraperitoneal route. Flammable liquid.
Dangerous fire hazard when exposed to heat
or flame. When heated to decomposition it
emits toxic fumes of Br-. See also
BROMIDES.
Purification Methods
Shake the bromide with conc H2SO4, wash with water, dry with K2CO3 and fractionally distil it. [Beilstein 1 IV 378.]
Check Digit Verification of cas no
The CAS Registry Mumber 107-82-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107-82:
(5*1)+(4*0)+(3*7)+(2*8)+(1*2)=44
44 % 10 = 4
So 107-82-4 is a valid CAS Registry Number.

Esterification of carboxylic acid salts

, (2008/06/13)
Mono- or polycarboxylic acid esters are prepared by reacting a salt of such carboxylic acid with an organic halocompound, e.g., a (cyclo)alkyl, (cyclo)alkenyl, aryl or aralkyl halide, in an aqueous reaction medium, in the presence of a catalytically effective amount of a phase transfer catalyst, for example an onium salt.
