일반 설명
Chloroplatinic acid hydrate is the most readily available compound of platinum. It may be prepared by dissolving platinum in aqua regia. Thermogravimetric analysis of this compound has been reported. The analysis shows the loss of water followed by formation of platinum tetrachloride (PtCl4) at 220 °C and β-PtCl2 at 350 °C finally decomposing to platinum metal at 500 °C.
애플리케이션
Chloroplatinic acid hydrate may be used:
- in the determination of potassium, by selective precipitation as potassium chloroplatinate.
- in the purification of platinum.
- In catalysis during the addition of silicon hydrides to olefinic double bonds and in platinum-catalyzed hydrosilylation of alkynes.
저장 및 안정성
1. Hygroscopic material, always handle in a glove bag or a glove box filled with dry inert gas
2. Recommended for one time use to prevent water absorption and degradation. If necessary, once opened, repack and seal under dry inert gas.
3. Store with care. Prevent from light. Always store in well-sealed containers in a dry inert atmosphere. Recommended to store containers in a secondary desiccator with desiccant in a dry inert atmosphere.

Cholinergic fast time-scale modulation of cortical physiology is critical for cognition, but direct local measurement of neuromodulators in vivo is challenging. Choline oxidase (ChOx)-based electrochemical biosensors have been used to capture fast cholinergic signals in behaving animals. However, these transients
