hydroxylamine
hydroxylamine Chem. (haɪˈdrɒksɪləˌmaɪn) [f. prec. + amine.] A basic substance, NH2OH, allied to ammonia, which combines with acids to form a well-defined series of salts. Discovered in 1865 by Lossen, but until 1891 known only in its salts or in aqueous solution.1869 Roscoe Elem. Chem. 216 Hydroxyla... Oxford English Dictionary

胲
如果烃基连接至氧原子处，就叫氧胲（O-hydroxylamine），而连接至氮原子处，就叫氮胲（N-hydroxylamine）。氧胲的通式是NH2O-R，而氮胲的通式可以是R-NOH或者RR'NOH。如果所有氢原子被取代，就会是RR'NOR。 来源 有机化合物 氧化合物 氢化合物 氮化合物 碳化物 en:Hydroxylamine#Functional group wikipedia.org
