1-胺基乙醇(英語:1-Aminoethanol)是一種有機化合物,化學式為CH3CH(NH2)OH。它被歸類為烷醇胺。具體來說,它是2-胺基乙醇的結構異構物。這兩種化合物的胺基位置不同。由於1-胺基乙醇的中心碳原子有四個不同的取代基,因此該化合物有兩種立體異構物。與在商業中相當重要的2-胺基乙醇不同,1-胺基乙醇不會作為純物質出現,主要具有理論意義。
1-胺基乙醇被認為是丙胺酸合成的斯特雷克反應的中間體。[2]
歷史
1-胺基乙醇於1833年由德國化學家約翰·沃爾夫岡·德貝萊納首先製備;其最簡式最早由德國化學家尤斯圖斯·馮·李比希於1835年確定。[3]1-胺基乙醇的結構直到1877年仍未得到證實,當時德裔義大利化學家羅伯特·希夫證明其結構為 CH3CH(OH)NH2。[4]

In 1821, Döbereiner had prepared what he called Saüerstoffäther (literally: ether oxide), which, as Liebig later showed, contained acetaldehyde. On p. 134, Liebig states that Döbereiner first produced 1-amino-ethanol by perfusing acetaldehyde (Saüerstoffäther or Aldehyd, as Liebig called it) with ammonia gas (Ammoniak) : "Der berühmte Entdecker des Acetals theilte mir damals gleichzeitig mit, dass sein Saüerstoffäther mit Ammoniakgas eine weisse krystallinische Verbingdung bilde; ... " (The famous discoverer of acetal [viz, Döbereiner] simultaneously communicated to me at that time that his ether oxide forms a white crystalline compound with ammonia gas; ... ) On p. 146, Liebig presented his empirical formula for 1-aminoethanol: C4H14N2O2. If the subscripts are divided by 2, the resulting formula is correct.
