A spectrophotometric method has been developed for the determination of aminophenol isomers (o-aminophenol, m-aminophenol and p-aminophenol). The method is based on oxidative coupling reaction of these compounds with 4-a...

Abstract A simple, rapid and highly sensitive spectrophotometric method has been described for the determination of dipyrone in a bulk and in dosage forms. The method depends on the organic oxidative coupling reaction of...

Abstract A simple spectrophotometric method has been developed for the determination of trifluoperazine hydrochloride in pure and in dosage forms. The method is based on the oxidative coupling reaction with sulfanilic ac...

the oxidation of promethazine by sodium hypochlorite and the coupling of the resulting product with metoclopraide in acetic acid medium to form a blue product with maximum absorption at 596 nm. Beer's law is obeyed over ...

Exposure to ambient air particulate matter (PM) is associated with increased cardiorespiratory morbidity and mortality. In this context, alveolar macrophages exhibit proinflammatory and oxidative responses as a result of...

Persistent synthetic dyes such as crystal violet pose substantial challenges to environmental remediation due to their high structural stability and toxicity. Here, we report a natural photobioelectrocatalytic strategy f...

Abstract Photo-redox catalysis has emerged as a new generation of biochemical protocols in proximity labeling, noninvasive therapy, ultrafast activation. However, the well-developed photocatalysts cannot simultaneously p...
