2-溴丙烷是一種有機化合物，化學式為C3H7Br，是丙烷的亞甲基氫被溴取代的產物。它的同分異構體是1-溴丙烷。它在2023年被列入IARC第2A類致癌物質。[6]
製備
異丙醇和溴化試劑（如硫酸-溴化鈉[8]、磷-溴[9]、三溴化磷[10]等）發生溴化反應，也能得到2-溴丙烷。
反應
2-溴丙烷可以用於合成異丙基化合物，例如在碳酸鉀的存在下，2-溴丙烷和4-羥基苯甲醛在乙腈中反應，可以得到4-異丙氧基苯甲醛；[11]碳酸銫作為鹼、四(三苯基膦)鈀作為催化劑，它和呋喃-2-硼酸反應，得到2-異丙基呋喃[12]。
它可以和碘化鈉在丙酮中發生鹵素交換反應，生成2-碘丙烷；[13]它和硫氰酸鈉發生類似反應，生成硫氰酸異丙酯。[14]它也可以和一氟化氯反應，生成2-氟丙烷。[15]
