In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Determination of 2-iminothiazolidine-4-carboxylic acid, published in 1965, which mentions a compound: 2150-55-2, mainly applied to , Electric Literature of C4H6N2O2S.
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.
In some applications, this compound(2150-55-2)Electric Literature of C4H6N2O2S is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
