Abstract

5‐astatouracil was prepared via the decomposition of the 5‐diazonium salt of uracil in the presence of ^211^At^−^ with overall yields ranging from 20 to 30%. Identification and separation was carried out on four different high pressure liquid chromatography columns. Under identical conditions, astatination is more effective than iodination, and complex formation of halide with the diazonium compound seems to be the product forming mechanism.

A rapid, precise, and simple HPLC method provides an assay of hydroxyproline from tissue extracts or solutions of collagen. Samples are hydrolyzed with 6 N HCl, derivatized with phenyl isothiocyanate, and chromatographed on a small, C18 reverse-phase HPLC column. Hydroxyproline (Hyp) is separated fr
