Urea as an active pharmaceutical ingedient is used mainly in dermatology for cremes and ointments and for ophthalmic applications. Urea crystalline Emprove^® API is manufactured under ICH Q7. A CEP and an US-DMF is available.

Used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. Useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.
