吡咯-2-羧酸乙酯用作色谱分析标准物质,并广泛应用于有机合成及制药工业。它主要用作聚酯纤维纺丝时的溶剂,还常用于金属防腐、环氧树脂固化、烯烃聚合催化剂以及医药原料等方面,同时也可用作光敏剂。
合成方法吡咯-2-羧酸乙酯的制备过程如下:将2,2,2-三氯-1-(1H-吡咯-2-基)-乙酮(25g,0.12mol)溶解在乙醇溶液中(200 mL),然后加入碳酸钾(5g)。加热至回流状态并保持1小时。随后过滤掉固体残留物,并通过减压浓缩处理该混合液。向此混合液中添加乙酸乙酯(200 mL),再用两次水洗涤。最后在Na2SO4上干燥有机相,得到淡黄色固体吡咯-2-羧酸乙酯(18g)。经HPLC分析,其质谱图显示m/z 140.12[M+H]⁺,核磁共振谱图(400.5 MHz,DMSO-d₆)δppm:1.29(t,J=7.0 Hz,3H),4.23(q,J=700 Hz,2H),6.25-6.04(m,1H),6.86-6.65(m,2H)。
