Preparation of carbon‐14 labelled guazatine

A method is described for small-scale laboratory simulation of the industrial process for the manufacture of guazatine, an agrochemical fungicide comprising a mixture of guanidated di-, tri-, and poly-amines derived from octamethylenediamine. The product has been prepared with carbon-14 labelling of the terminal positions of the octamethylene chains. Copyright © 2001 John Wiley & Sons, Ltd.
