The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid, is researched, Molecular C4H6N2O2S, CAS is 2150-55-2, about Plasma persistence of 2-aminothiazoline-4-carboxylic acid in rat system determined by liquid chromatography tandem mass spectrometry, the main research direction is aminothiazoline carboxylate determination HPLC tandemMS blood forensic diagnostic biomarker.Synthetic Route of C4H6N2O2S.
2-Aminothiazoline-4-carboxylic acid (ATCA) was i.v. injected to rats to investigate its blood plasma distribution. ATCA was extracted from plasma samples by solid phase extraction (SPE) and molecularly imprinted polymer stir bar sorption extraction (MIP-SBSE). Detection and quantification of ATCA were achieved by liquid chromatog.-tandem mass spectrometry (LC-MS/MS). It was found that the i.v. injected ATCA concentration quickly decreased to half within 2.5 h in the rat system. However, after 2.5 h, the concentration of ATCA in plasma stayed constant at least 5 folds above the endogenous ATCA level for more then 48 h. This finding can be used for evaluating ATCA’s diagnostic and forensic value as a biomarker for cyanide exposure.
