2-Methylbenzoxazole Usage And Synthesis
Chemical Properties
clear colourless to yellow liquid
Chemical Properties
Yellowish liquid, solidifying in the cold.
Insoluble in water, soluble in alcohol, miscible with most oils.
Very sweet odor of rather gassy-pungent
character when undiluted, becoming floralsweet, heavy, when diluted.
Uses
2-Methylbenzoxazole has been used in synthesis of bis-styryl dyes. It is also used in medicine and for the synthesis of other organic compounds.
Production Methods
2-Methylbenzoxazole can be produced from ortho-Aminophenol plus Acetic anhydride by heating and distilling.
Definition
ChEBI: A member of the class of 1,3-benzoxazoles that is 1,3-benzoxazole substituted by a methyl group at position 2.
Aroma threshold values
High strength odor, tobacco type; recommend smelling in a 0.10% solution or less.
Synthesis Reference(s)
