3-Propyl-5-hydroxy-5-D-arabinotetrahydroxybutyl-3-thiazolidine-2-thione, a specific colorimetric reagent for the determination of copper in water

Abstract

The 3-propyl homologue of 3-methyl-5-hydroxy-5-D-arabinotetrahy-droxybutyl-3-thiazolidine-2-thione has been prepared and used as a reagent in the colorimetric determination of copper in water. Interference by other metals and by cyanide has been examined; inhibition of complex formation by cyanide appears to be almost quantitative.
