“…It was also seen that the samples that were forcibly degraded by strong base and oxidation developed a brownish yellow colour at the end of the 4 days. As pseudomorphine is colourless (1,5), the above observation may support the postulation of some authors that colour development could be due to the decomposition products of pseudomorphine or other compounds (5).…”

“…phine-N-oxide in the ratio 9:l with a trace of a base, believed to be methylamine (1)(2)(3)(4)(5)(6)(7), is also dependent on the presence of excess oxygen (6). As the volume fill of the formulation in the mixture container is decreased, the rate of morphine loss increases substantially (8-10).…”
This study demonstrated that the concentrating effect due to evaporation under the storage conditions described, over 16 days, was not of significance and the product was stable.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
