Description

General description

4-Imidazoleacrylic acid also known as urocanic acid is a natural metabolite derived from histidine. It is majorly used as a UV chromophore with a strong absorption spectrum in the UV-B region in the range of 300-280 nm.

Application

4-Imidazoleacrylic acid can be used as a precursor for the synthesis of (±)-homohistidine, urocanic acid-modified chitosan, and N¹-aryl(heteroaryl)alkyl-N²-[3-(1H-imidazol-4-yl)propyl]guanidines,.
