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,.

Hair analysis has become an integral part in forensic toxicological laboratories for e.g. assessment of drug or alcohol abstinence. However, hair samples can be manipulated by cosmetic treatments, altering drug concentrations which eventually leads to false negative hair test results.
