3-Chloropropanoic acid (also known as 3-chloropropionic acid or UMB66) is the organic compound with the formula ClCH2CH2CO2H. A white or colorless solid, it is used as a drug and a synthetic intermediate. The compound is produced by the hydrochlorination of acrylic acid.[1] In aqueous solution, it has a pKa value of 4.08.[2]
This compound is used in scientific research. It is structurally related to GHB and binds to the GHB receptor, but has no affinity for GABA receptors.[3] It is also an active ingredient in some herbicide blends.[4] Overdose may cause unconsciousness and/or convulsions.[5] It has been demonstrated that the substance can be broken down by both bacteria and fungi as a means of bioremediation.[6][4]
