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)

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.
