The mucolytic agent bromhexine is useful in the evaluation of the performance of inductively coupled plasma mass spectrometry (ICP-MS) as compared to radiolabelling. A prerequisite for this comparison is access to radiolabelled bromhexine. [ 3 H 2 ]bromhexine was synthesized in three steps introduci

✦ Synopsis
Paichongding and Cycloxaprid are two novel neonicotinoids with good industrialization prospects for their high activity against imidacloprid-resistant pest. In this paper, the radiosynthesis of [ 3 H 2 ]-Paichongding and [ 3 H 2 ]-Cycloxaprid was achieved using a NaB 3 H 4 reduction. The title compounds were obtained with chemical purities of 98.7 and 98.4%, and radiochemical purities of 97.3 and 98.6%, respectively. The labeled compounds could be used as radiotracers for further study of metabolism and toxicology.
