The impurity is a natural product and an API impurity. The impurity is synthesized by the rearrangement of (E/Z)-FK-506 26,28-allylic ester. This impurity has been shown to be present in drug products at concentrations up to 0.0025% w/w. It is found in analytical samples at concentrations up to 0.02% w/w, which may be due to its use as a HPLC standard. The impurity has been studied for metabolism in rats and rabbits and is not metabolized by microsomal enzymes or conjugated with glucuronic acid. The compound has also been shown to have anti-inflammatory properties in mice models and has no cardiotoxic effects on Balb/c mice.

Imipramine N-oxide hydrate is a drug product that is used in the synthesis of other drugs. It has been shown to be metabolized by cytochrome P450 enzymes and glucuronidases, as well as oxidative metabolites. Imipramine N-oxide hydrate is a metabolite of imipramine.

Applications A labelled metabolite of Erlotinib (E625000), an anti cancer agent. References Rusch, V., et al.: Cancer Res., 53, 2379 (1993), Fontanini, G., et al.: Clin. Cancer Res., 4, 241 (1998), Comis, R., et al.: Oncologist, 10, 467 (2005), Ling, J., et al.: Drug Metab. Dispos., 34, 420 (2006),
