1-氨基乙醇（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-氨基乙醇的結構異構體。這兩種化合物的氨基位置不同。由於1-氨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體。與在商業中相當重要的2-氨基乙醇不同，1-氨基乙醇不會作為純物質出現，主要具有理論意義。

1-氨基乙醇存在於乙醛和氨水的溶液中。^[1]

1-氨基乙醇被認為是丙氨酸合成的斯特雷克反應的中間體。^[2]

歷史

1-氨基乙醇於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-氨基乙醇的結構直到1877年仍未得到證實，當時德裔意大利化學家羅伯特·希夫證明其結構為 CH₃CH(OH)NH₂。^[4]
