Cyclobutanecarboxylic acid is the organic compound with the formula C₄H₇CO₂H. It is a colorless nonvolatile liquid. It can be prepared by decarboxylation of 1,1-cyclobutanedicarboxylic acid.^[2] Cyclobutanecarboxylic acid is an intermediate in organic synthesis. For example, it is a precursor to cyclobutylamine.^[3]
