Principles in the Spectrophotometric Determination of Propoxycaine in the Presence of Procaine**Division of Chemistry, American Dental Association, Chicago, Ill.
“…With suitable standard solutions this fact can be utilized for determination of concentration in dosage forms containing only one local anesthetic, or, in special cases, the absorption data can be used in the determination of each of two local anesthetics (11). In some instances the spectra depend on the pH of the solvent solution.…”

“…In the event that subsequent quantitative analysis is required, spectrophotometric analysis, or especially in the case of mixtures, more specific methods of analysis such as those previously reported (5,10,11), can be used.…”

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.
