General description

2-Amino-4-methylphenol is the major sensitizer in contact allergy to Disperse Yellow 3. It reacts with acetylacetone in absolute ethanol to yield 4-(2-hydroxy-5-methylphenyl)imino-2-pentanone. It was converted to dihydrophenoxazinone by purified human hemoglobin.

Application

2-Amino-4-methylphenol was used in the synthesis of novel functionalized spiropyran derivatives of 2H-1,3-benzoxazinone series.

In spite of the variety of initial reactions, the aerobic biodegradation of aromatic compounds generally yields dihydroxy intermediates for ring cleavage. Recent investigation of the degradation of nitroaromatic compounds revealed that some nitroaromatic compounds are initially converted to 2-aminophenol rather
