화학적 성질

white to beige fine powder

용도

Urocanic Acid is a biomarker in the fecal metabolic profiling of breast cancer patients.

정의

ChEBI: An alpha,beta-unsaturated monocarboxylic acid that is prop-2-enoic acid substituted by a 1H-imidazol-4-yl group at position 3. It is a metabolite of hidtidine.

일반 설명

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.

Purification Methods

Crystallise the acid from water and dry it at 100o. The trans-isomer [3465-72-3] has m 225o (229-230o, 230-231o or 231o(dec, from H2O) and pK1 3.5 and pK2 5.6, and the picrate has m 225o(dec, from H2O). The cis-isomer [7699-35-6] has m 175-176o (178-179o or 180-184o dec, from H2O) and pK1 3.0 and pK2 6.7, and the picrate has m 204o (from H2O).
