摘要：The application discloses L- and DL-2-guanidino-1,3-thiazoline carboxylic acid-4 and its tautomere, L- and DL-2-guanidino-1,3-thiazolidine carboxylic acid-4, as well as their basic copper salts, and a method of making these novel and useful compositions by reacting cysteine hydrochloride and dicyandiamide. In addition, advantageous uses of these compositions are disclosed, notably, for instance, as precipitating agents for inorganic or organic acids, and as means for separating the optical antipodes of the racemates of optically active acids.
