Description

Application

• Determination of phosphorylated and O-glycosylated sites by chemical targeting (CTID) at ambient temperature.: This study explores the use of chemical targeting to identify phosphorylated and O-glycosylated sites, essential for understanding protein modifications. Barium hydroxide is utilized for its effectiveness in ambient temperature conditions, contributing to more efficient analytical methods (Hathaway, 2007).


• Wet-chemical synthesis of crystalline BaTiO3 from stable chelated titanium complex: formation mechanism and dispersibility in organic solvents.: The research demonstrates the wet-chemical synthesis of BaTiO3, highlighting the formation mechanism and its dispersibility. Barium hydroxide plays a crucial role in stabilizing the chelated titanium complex, making it a valuable component in material synthesis and analytical chemistry (Pramanik et al., 2006).


• Synthesis and analgesic effect of normorphine-3- and -6-glucuronides.: This paper details the synthesis of normorphine glucuronides, where barium hydroxide is used in the synthetic process. The study contributes to the understanding of analgesic properties and the chemical synthesis of pharmacologically relevant compounds (Oguri et al., 1989).
