애플리케이션
Potassium hydride can be used for following applications:
- Deprotonation: As a strong base, potassium hydride effectively deprotonates hydroxyl groups of monomers, generating alkoxide ions. These ions facilitate the ring-opening polymerization of monosubstituted oxiranes.
- Strong Base in Williamson Ether Synthesis: It is employed to generate alkoxides from alcohols, which subsequently react with alkyl halides to form ethers.
- Reducing Agent: Potassium hydride can reduce hindered boranes and borates to trialkyl borohydrides. It also facilitates the reduction of ketones and alkyl halides.
- Alkylation and Enolate Formation: It aids in the formation of enolates from ketones, which can be utilized in one-pot alkylation-cyclization reactions.

Hyperkalaemia in heart failure patients limits use of cardioprotective renin-angiotensin-aldosterone system inhibitors (RAASi). Sodium zirconium cyclosilicate (ZS-9) is a selective potassium ion trap, whose mechanism of action may allow for potassium binding in the upper gastrointestinal tract as early as

Hyperkalemia (serum potassium level, >5.0 mmol per liter) is associated with increased mortality among patients with heart failure, chronic kidney disease, or diabetes. We investigated whether sodium zirconium cyclosilicate (ZS-9), a novel selective cation exchanger, could lower serum potassium levels

Calcium imaging of individual neurons is widely used for monitoring their activity in vitro and in vivo. Synthetic fluorescent calcium indicator dyes are commonly used, but the resulting calcium signals sometimes suffer from a low signal-to-noise ratio (SNR). Therefore, it
