'''异戊酸'''([[結構式]]:([[碳|C]][[氫|H]]<sub>3</sub>)<sub>2</sub>[[碳|C]][[氫|H]][[碳|C]][[氫|H]]<sub>2</sub>[[碳|C]][[氧|O]][[氧|O]][[氫|H]])，是一种含有5个[[碳原子]]的[[短链饱和脂肪酸]]。透明液体，可溶于水。

==性质==
无色，具有强烈难闻气味的透明液体。溶于水，与[[乙醇]]、[[乙醚]]混溶。

==制备==
由[[异戊醛]]经[[催化]][[氧化]]而得。
:<math>\mathrm{(CH_3)_2CHCH_2CHO+\tfrac{1}{2} O_2\rightarrow (CH_3)_2CHCH_2COOH}</math>

==用途==
