異氰基乙酸乙酯是一種有機化合物，化學式為C₅H₇NO₂。根據一份2020年的統計，它是在學術研究中第五常見的異腈。^[3]它可由N-甲醯基甘胺酸乙酯和光氣（或三氯氧磷^[4]）在三乙胺存在下於二氯甲烷中反應得到。^[2]

反應

異氰基乙酸乙酯在催化下和乙醛反應，可以得到4,5-二氫-5-甲基-4-㗁唑甲酸甲酯，反應同時產生4S-反式異構物和4R-順式異構物，比例84:16。^[5]它和己醛在對甲苯磺酸鈉存在下於水中反應，可以得到N-(2-羥基-1-氧代庚基)甘胺酸乙酯。^[6]

它在氫氧化鉀溶液中水解，生成異氰基乙酸鉀。^[7]

CNCH₂COOC₂H₅ + KOH → CNCH₂COOK + C₂H₅OH

它和磺醯氯在三氯甲烷中反應，可以得到N-二氯亞甲基甘胺酸乙酯。^[8]

在氯化銅、鄰菲囉啉和碳酸銫存在下，它和芳胺、二氟氯乙酸鈉反應，可以得到相應的芳基咪唑甲酸乙酯。^[9]
