Product Overview
This 12% sodium borohydride solution in 40% aqueous sodium hydroxide (NaOH) is a highly effective reducing agent designed for precise and controlled chemical reactions in laboratory settings. The AcroSeal® packaging ensures maximum stability and purity, preventing contamination and degradation over time. Sodium borohydride is widely recognized for its ability to selectively reduce aldehydes, ketones, and other functional groups without affecting double bonds or aromatic systems, making it a versatile choice for synthetic applications. The solution is prepared in a stabilized alkaline medium, which enhances its shelf life while maintaining reactivity. Its liquid form allows for easy handling and accurate dosing, reducing the risk of exposure compared to solid forms. The product is compatible with standard laboratory glassware and can be safely stored under recommended conditions. Whether used in small-scale experiments or larger preparative work, this solution delivers consistent performance, ensuring reproducible results in research and development environments.
FAQs
1. What is the shelf life of this sodium borohydride solution?
The solution remains stable for up to 12 months when stored unopened in its original AcroSeal® packaging at room temperature, away from moisture and direct sunlight. Once opened, it should be used within 6 months for optimal performance.
2. Can this solution be used with other solvents?
While primarily used in aqueous systems, it can be combined with protic solvents like methanol or ethanol under controlled conditions. Avoid mixing with acidic solvents, as this can lead to rapid decomposition and hydrogen gas evolution.
3. Are there any safety precautions for handling this product?
Always wear protective gloves, goggles, and a lab coat when handling. Work in a well-ventilated fume hood, as the solution can release hydrogen gas upon contact with acids or water. Neutralize spills with dilute acetic acid before cleanup.
4. What alternatives exist if this concentration is too strong?
Lower concentrations (e.g., 5% or 8% solutions) are available for less aggressive reductions. Solid sodium borohydride can also be dissolved in compatible solvents to prepare custom concentrations as needed.
5. How should this solution be disposed of after use?
Neutralize excess solution with a dilute acid (e.g., 10% hydrochloric acid) in a controlled manner to decompose the borohydride. Follow local hazardous waste disposal regulations for the neutralized mixture.
