The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Determination of 2-iminothiazolidine-4-carboxylic acid》. Authors are Bradham, L. S.; Catsimpoolas, Nicholas; Wood, John L..The article about the compound:2-Amino-4,5-dihydrothiazole-4-carboxylic acidcas:2150-55-2,SMILESS:O=C(C1N=C(N)SC1)O).Product Details of 2150-55-2. Through the article, more information about this compound (cas:2150-55-2) is conveyed.
Procedures are described for determination of 2-iminothiazolidine-4-carboxylic acid, using diazotized sulfanilic acid or the mercury-diphenylthiocarbazone reaction. The compound should first be separated from interfering substances such as are found in urine. Paper electrophoresis, ion displacement, or chromatography suffice for this purpose.
There is still a lot of research devoted to this compound(SMILES：O=C(C1N=C(N)SC1)O)Product Details of 2150-55-2, and with the development of science, more effects of this compound(2150-55-2) can be discovered.
