Aminophenol

Japanese: アミノフェノール
Aminophenol
(chemical formula) A compound in which the hydrogen atom on the benzene nucleus of phenol is replaced with an amino group -NH2 . This usually refers to a compound with one amino group, and there are three isomers: o- , m- , and p- . The p -isomer is produced by reducing p -phenylazophenol, which is produced by the reaction of phenol with a diazonium salt, with hydrosulfite Na2S2O4 . (chemical formula) Aminophenols are easily oxidized to quinones. For this reason , they are used as photographic developers (Rodinal, Metol, Amidol, etc.).

Japanese:
(化学式)フェノールのベンゼン核についている水素原子をアミノ基-NH2で置換した化合物。ふつうはアミノ基が一つのものをさし,これにはo‐,m‐,p‐の3異性体が存在する。p‐体はフェノールとジアゾニウム塩の反応で生ずるp‐フェニルアゾフェノールをハイドロサルファイトNa2S2O4で還元して作る。(化学式)アミノフェノールは容易に酸化されてキノンになる。このため写真の現像液(ロジナール,メトール,アミドールなど)として使われている。
