Description

Application

• SPECTROPHOTOMETRIC DETERMINATION OF THYMOL IN MOUTHWASHES VIA SODIUM NITROPRUSSIDE REACTION WITH HYDROXIDE AMINE HYDROCHLORIDE.: This study presents a spectrophotometric method for determining thymol in mouthwashes using a reaction with sodium nitroprusside and hydroxide amine hydrochloride. This analytical approach enhances the accuracy and reliability of thymol quantification in pharmaceutical products (International Journal of Research in Pharmacy and Chemistry, 2023).


• Efficacy of postharvest sodium nitroprusside application to extend storability by regulating physico-chemical quality of pear fruit.: This study investigates the application of sodium nitroprusside in extending the storability of pear fruits by regulating their physico-chemical quality. The findings suggest significant improvements in fruit preservation and quality maintenance during storage (Food Chemistry, 2021).
