Product Overview
Choline hydroxide, supplied as a 45 wt.% aqueous solution, is a quaternary ammonium base widely used in laboratory settings for its strong alkaline properties. This high-purity reagent serves as an effective phase-transfer catalyst and pH regulator in biochemical and organic synthesis applications. The solution is clear, colorless to pale yellow, and miscible with water, ensuring easy integration into experimental protocols. Its stability under standard lab conditions makes it a reliable choice for researchers requiring consistent reactivity. The 45% concentration provides an optimal balance between solubility and reactivity, reducing the need for further dilution in most procedures. Compatible with glass and most plastic labware, this solution minimizes contamination risks while maintaining reagent integrity. Whether used for ion exchange, extraction processes, or as a base in chemical reactions, this choline hydroxide solution delivers reproducible results for demanding laboratory applications.
FAQs
1. What is the shelf life of 45% choline hydroxide solution?
The solution remains stable for 24 months when stored unopened in its original container at room temperature. Always check for precipitation or color changes before use.
2. Can this solution be used with metal containers?
Avoid metal containers as the alkaline nature may cause corrosion. Use glass or HDPE plastic containers for storage and handling.
3. Is this choline hydroxide solution compatible with DMSO?
Yes, it is miscible with DMSO, but pre-testing is recommended for specific applications to ensure no unwanted side reactions occur.
4. What safety precautions should be taken while handling?
Wear nitrile gloves, safety goggles, and work in a fume hood. The solution is corrosive and can cause skin and eye irritation upon contact.
5. Are there any known impurities in this grade?
This laboratory-grade solution contains ≤0.5% residual water and trace chlorides. For ultra-pure requirements, further purification may be necessary.
