Chloroalanine is an unnatural amino acid with the formula ClCH₂CH(NH₂)CO₂H. It is a white, water-soluble solid. The compound is usually derived from chlorination of serine. The compound is used in the synthesis of other amino acids by replacement of the chloride.[1] Protected forms of the related iodoalanine are also known.[2][3] It is a substrate for 3-chloro-D-alanine dehydrochlorinase.
