主要用于新型农药、医药和染料等的生产，在材料、溶剂等领域也有较大的应用开发潜力。三氟乙酸主要用于合成多种含三氟甲基和杂环的除草剂，目前可以合成多种带有吡啶基、喹啉基的新型除草剂；作为极强的质子酸，它广泛用于芳香族化合物烷基化、酰基化、烯烃聚合等反应的催化剂；作为溶剂，三氟乙酸是氟化、硝化及卤代反应的优良溶剂，特别是其衍生物三氟乙酰基对羟基和氨基的优良保护作用，在氨基酸和多肽化合物合成方面有着非常重要的应用,用于多肽合成中除去氨基酸的叔丁氧羰基（t-boc）保护基；三氟乙酸作为制备离子膜的原料和改性剂，可大幅提高烧碱工业电流效率，延长膜的使用寿命；三氟乙酸还可合成三氟乙醇、三氟乙醛和三氟乙酐。室温下三氟乙酸汞使氟苯起汞化反应（亲电取代），也可将腙转化为重氮化合物。此酸的铅盐可将芳烃转化为酚。
