title: On the stability of a tin-phytate complex.
abstract: The stability of tin-phytate solution stored at room temperature has been studied. It was found that there is a pronounced increase in the rate of degradation of this complex, both temperature and phase change contributing to the enhanced rate of decomposition. The kidney uptake which is occasionally observed clinically with an aged tin-phytate complex labelled with 99mTc is probably due to an intermediate product which subsequently breaks down on further storage. Lyophilized tin-phytate complex 'kits' have a longer shelf life than the aqueous complex.
