1,2,3,4-Butanetetracarboxylic acid is an organic compound with the formula HO2CCH2CH(CO2H)CH(CO2H)CH2CO2H.

The compound is produced by oxidation of tetrahydrophthalic anhydride.

[1] Among the several possible uses, it has been repeatedly investigated in the textile industry,[2] e.g., for permanent press clothing.

[3] As expected for a polycarboxylate, it binds zinc to afford coordination polymers.

[4] It forms a dianhydride (RN 4534-73-0), which consists of two succinic anhydride-like rings.
