| | 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. | | Definition | ChEBI: A member of the class of 1,3-benzoxazoles that is 1,3-benzoxazole substituted by a methyl group at position 2. | | Production Methods | 2-Methylbenzoxazole can be produced from ortho-Aminophenol plus Acetic
anhydride by heating and distilling. | | Aroma threshold values | High strength odor, tobacco type; recommend smelling in a 0.10% solution or less. | | Synthesis Reference(s) | Tetrahedron Letters, 37, p. 675, 1996 DOI: 10.1016/0040-4039(95)02240-6 | | Biochem/physiol Actions | Odor at 1.0%: Musty, nutty pecan, almond and pistachio-like, tobacco, vanilla-like with brown roasted burnt rubber and cooked rice-like nuances.Taste at 2.0ppm: Musty, nutty, vanilla and rice-like. |
