Hi,I am wondering if anyone knows where I can obtain some C14 labeled picloram (4-amino-3,5,6-trichloropicolinic acid). Picloram is a herbicide manifactured by Dow Chemical Co. under the trademark name of Tordon. Chemical suppliers such as Sigma and Aldrich do not carry the radiolabeled picloram. I would appreciate your help. Thanks, Bettina.
