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 Zwitterion structure and acylative ring-opening reactions of 2-aminothiazoline-4-carboxylic acid, published in 1962, which mentions a compound: 2150-55-2, mainly applied to , Related Products of 2150-55-2.
pKA values (pK1 2.03, pK2 8.48), variation of optical rotation with pH and other phys. properties indicate that 2-aminothiazoline-4-carboxylic acid is a zwitterion in solution and in the solid state anti that pK2 can be ascribed to ionization from the ring nitrogen. Acylation of 2-aminothiazoline-4-carboxylic acid in aqueous medium is accompanied by ring opening. With Ac2O N’, S-diacetyl-N-carbamoylcysteine is obtained and with BzCl S-benzoyl-N-carbamylcysteine and 2-imino-3-benzoylthiazolidine-4-carboxylic acid are obtained. Structures of the acylated products were proven by chem. methods and by interpretation of nuclear magnetic resonance data
As far as I know, this compound(2150-55-2)Related Products of 2150-55-2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
