2-Chloro-1,4-dimethylbenzene Usage And Synthesis

Chemical Properties	Clear colourless to light yellow liquid
Uses	2-Chloro-1,4-dimethylbenzene may be used in chemical synthesis studies.
General Description	A colorless liquid. Flash point below 141°F. May be irritating and narcotic in high concentrations. Used as a solvent and for making other chemicals and dyes. Density about 8.9 lb / gal.
Air & Water Reactions	Highly flammable. Slightly soluble in water.
Reactivity Profile	Simple aromatic halogenated organic compounds, such as 2-Chloro-1,4-dimethylbenzene, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Health Hazard	Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
