Product Overview
Tetramethylammonium hydroxide (TMAH), presented as a 10% aqueous solution, is a quaternary ammonium compound renowned for its strong basic properties and solubility in polar solvents. This BAKER ANALYZED™ reagent-grade solution undergoes rigorous quality control to ensure consistent purity and performance in demanding laboratory environments. The 10% concentration provides an optimal balance between reactivity and ease of handling, making it particularly suitable for applications where precise alkalinity control is required. The solution’s stability and low volatility at room temperature contribute to its reliability in prolonged experimental setups. As a reagent-grade product, it meets stringent specifications for trace metal impurities and organic contaminants, ensuring minimal interference in sensitive analytical procedures. The aqueous formulation eliminates the need for additional dissolution steps while maintaining the compound’s characteristic strong base behavior. This particular preparation is especially valued in protocols where water-soluble organic bases are preferred over traditional inorganic hydroxides, offering compatibility with a wider range of reaction conditions.
FAQs
1. What is the shelf life of this 10% TMAH solution when stored properly?
When stored in its original tightly sealed container at room temperature, away from direct sunlight and moisture, this solution typically maintains its specified properties for 12-18 months from the date of manufacture.
2. How does this solution compare to solid TMAH pentahydrate in terms of handling?
The 10% aqueous solution offers easier handling and more precise dosing compared to solid forms, eliminating the need for weighing and dissolution steps while providing immediate availability of the active base.
3. What type of container material is recommended for long-term storage of this solution?
Polyethylene or polypropylene containers are recommended for storage as they resist the alkaline nature of the solution better than glass containers over extended periods.
4. Does this solution require any special disposal procedures?
As with all quaternary ammonium compounds, this solution should be neutralized before disposal according to local environmental regulations, typically by careful acidification followed by appropriate chemical waste treatment.
5. What is the typical pH range for this 10% TMAH solution?
The solution typically exhibits a pH between 13-14 due to its strong basic nature, though the exact value may vary slightly depending on temperature and storage conditions.
