Product Name – Tetramethylammonium hydroxide, 10% in water Quantity/Pack Size – 1KG, 100GR, 500GR Form – Liquid solution Grade – Reagent grade Application – Analytical chemistry, organic synthesis
Product Overview
Tetramethylammonium hydroxide (TMAH), supplied as a 10% aqueous solution, is a quaternary ammonium compound widely recognized for its strong basicity and stability in laboratory environments. This reagent-grade solution offers a non-volatile, non-nucleophilic base, making it an excellent choice for applications requiring controlled alkalinity without residual impurities. The 10% concentration ensures ease of handling while maintaining high reactivity, particularly in organic synthesis, photoresist development, and analytical procedures. Its water-based formulation eliminates the need for additional solvents, simplifying workflows and reducing preparation time. The solution is highly stable under standard storage conditions, ensuring consistent performance across repeated use. Compatible with most glass and plastic labware, it minimizes the risk of contamination or degradation. Whether used as a titrant, catalyst, or etching agent, this TMAH solution delivers reliable results with minimal batch-to-batch variation, making it a dependable addition to any laboratory inventory.
FAQs
1. What is the shelf life of this 10% TMAH solution?
The solution remains stable for up to 24 months when stored in a tightly sealed container at room temperature, away from direct sunlight and moisture. Always check for precipitation or color changes before use.
2. Can this solution be used with standard glassware?
Yes, it is fully compatible with borosilicate glass and most high-density polyethylene (HDPE) or polypropylene (PP) containers. Avoid prolonged contact with metals or reactive plastics to prevent degradation.
3. Is this TMAH solution suitable for semiconductor applications?
While it is commonly used in photoresist development, ensure the grade meets specific purity requirements for semiconductor fabrication. This reagent-grade solution is ideal for general lab use but may require further purification for high-end electronics.
4. How should I dispose of unused or expired solution?
Neutralize with a dilute acid (e.g., hydrochloric acid) before disposal, following local hazardous waste regulations. Never discard untreated TMAH down drains or in regular trash due to its corrosive nature.
5. Are there any known incompatibilities with other chemicals?
Avoid mixing with strong oxidizing agents, acids, or halogenated compounds, as violent reactions may occur. Always refer to a compatibility chart or conduct small-scale tests before combining with other reagents.
