| | Benzoxazole Usage And Synthesis |
| Chemical Properties | COLORLESS TO YELLOW CRYST. LOW MELTING SOLID | | Uses | Benzoxazole derivatives serve as precursors for synthesizing heterocyclic compounds with anticorrosive and complexing properties, including N-substituted-3-methyl-1-(5-methyl-1,3-benzoxazol-2-yl)-1H-pyrazol-5-amines from 2-hydrazinyl-5-methyl-1,3-benzoxazole and 3-aminocrotonitrile, as well as 2-[(4-chloro-1,3-benzoxazol-2-yl)sulfanyl]-N-[phenylmethylidene]acetohydrazides from reactions with aromatic aldehydes[1]. | | Definition | ChEBI: A benzoxazole in which the benzene ring is fused to a 1,3-oxazole ring across positions 4 and 5. | | Safety Profile | Poison by intraperitoneal andintravenous routes. Moderately toxic by ingestion. Whenheated to decomposition it emits toxic fumes such asNOx. | | References | [1] Alami, A. E., Maraghi, A. E., & Sdassi, H. (2024).
