Labetalol EP impurity D is a metabolite of labetalol that is used as an impurity standard for HPLC. This impurity has been identified in the drug product and also in the drug development process. Labetalol EP impurity D is one of many metabolites that can be formed by cytochrome P450 enzymes. Labetalol EP impurity D is a natural metabolite of labetalol, which can be found in the urine of humans and other mammals. It is also present in various plants and fungi, including mushrooms, lichens, yeast, and barley. Synthetic labetalol EP impurity D can also be produced by various chemical reactions.

Applications Carvedilol is a nonselective β-adrenergic blocker with α1-blocking activity. Carvedilol is an antihypertensive used in the treatment of congestive heart failure. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Hirohashi, M., et al.: Arzneim.-Forsch., 40, 735 (1990); Packer, M., et al.: N.
