Application
- One-Pot Synthesis and in Silico Molecular Docking Studies of Arylselanyl Hydrazides as Potential Antituberculosis Agents.: This research illustrates the utilization of 50% Hypophosphorous acid in the synthesis of arylselanyl hydrazides, emphasizing its role as a reducing agent to facilitate novel antituberculosis compounds, reflecting its significance in medicinal chemistry applications (Borges et al., 2022).
- Formation of Thick Aminophenyl Films from Aminobenzenediazonium Ion in the Absence of a Reduction Source.: This study explores the action of 50% Hypophosphorous acid in the spontaneous formation of aminophenyl films from diazonium ions without additional reducing agents, highlighting its potential in surface coating processes (Simons et al., 2014).
