In chemistry, the amino radical, ·NH2, also known as the aminyl or azanyl, is the neutral form of the amide ion (NH− 2). Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry. In sufficiently high concentration, amino radicals dimerise to form hydrazine.

氨基（Amino）由一个氮原子和两个氢原子构成，化学式为-NH2。在有机化学中，氨基是基本碱基，大多数含有氨基的有机物都有一定碱的特性，

Jul 30, 2021 · What is the Azanide ion? NH2- is often confused with the organic amide group. This article on its Lewis Structure, geometry, and hybridization will help differentiate the two.

Mar 18, 2020 · El grupo amino es aquel que está presente en varios compuestos orgánicos nitrogenados, por ejemplo las aminas, y se representa con la fórmula -NH2. Las aminas son los compuestos más representativos donde encontramos a este grupo, ya que cuando son alifáticas tienen por fórmula RNH2; mientras que cuando son aromáticas, tienen por fórmula ...

Imines can be hydrolyzed back to the corresponding 1 o amine under acidic conditions. A wide variety of substances with −NH 2 groups can react with aldehydes and ketones by an addition-elimination sequence to yield compounds with a carbon-nitrogen double bond.
