Mucobromic acid is an organic compound that consists of a dibrominated alkene with aldehyde and carboxylic acid functional groups. It easily tautomerizes to a furanone hemiacetal form. This compound, and the analogous mucochloric acid (CAS #87-56-9), form the group of known mucohalic acids. The bromide appears to behave similarly to the more heavily studied chloride.
