General description
Sodium hydroxide, also known as lye and caustic soda, is a strong base used universally as a neutralization agent in the chemical industry, paper making, petroleum refining, cleaning compounds, and drain cleaners.
Application
Sodium hydroxide can be used as:
- A reagent in the gold-catalyzed selective oxidation of glycerol to glyceric acid.
- A catalyst for the cross-dehydrogenative coupling of alcohols and hydrosilanes to synthesize silyl ethers.
- A base in the Sonogashira-type coupling of aryl halides and alkynes to synthesize ynones.

Polyphosphate (polyP) is secreted by activated platelets and has been shown to contribute to thrombosis, suggesting that it could be a novel antithrombotic target. Previously reported polyP inhibitors based on polycationic substances, such as polyethylenimine, polyamidoamine dendrimers, and polymyxin B
