Product Overview
Hydrogen chloride (HCl) in 1,4-dioxane is a high-purity, 4N (99.99%) solution designed for demanding laboratory applications where precise acidity and solvent compatibility are critical. The AcroSeal® packaging ensures long-term stability by minimizing moisture absorption and contamination, preserving the reagent’s integrity for consistent performance. This solution is particularly valued in organic synthesis for its ability to act as a strong acid catalyst without introducing water, making it ideal for reactions sensitive to hydrolysis. The 1,4-dioxane solvent enhances solubility for organic substrates while maintaining the acidic properties of HCl, enabling efficient protonation and reaction control. The sealed format reduces exposure risks and extends shelf life, making it a reliable choice for research and development workflows. Whether used in esterifications, Friedel-Crafts reactions, or as a titrant in analytical procedures, this solution delivers reproducible results with minimal batch-to-batch variation. Its compatibility with anhydrous conditions further broadens its utility in moisture-sensitive processes, ensuring versatility across diverse experimental setups.
FAQs
1. What is the shelf life of hydrogen chloride 4N in 1,4-dioxane under proper storage?
The solution remains stable for up to 24 months when stored unopened in its original AcroSeal® packaging at room temperature, away from direct sunlight and moisture. Once opened, use within 6 months for optimal performance.
2. Is this solution compatible with glassware, or does it require special containers?
While the solution can be handled in standard borosilicate glassware, prolonged storage in glass may lead to minor etching due to the acidic nature. For long-term storage, use PTFE-lined or HDPE containers to prevent contamination.
3. Can this be used as a substitute for anhydrous HCl gas in reactions?
Yes, this 4N solution in 1,4-dioxane can replace anhydrous HCl gas in many applications, offering easier handling and precise dosing. However, for reactions requiring extremely dry conditions, additional drying agents may be needed.
4. What precautions should be taken when handling this solution?
Always use in a fume hood with proper PPE, including gloves, goggles, and a lab coat. Avoid inhalation of vapors and skin contact, as 1,4-dioxane is a suspected carcinogen and HCl is highly corrosive.
5. How does the AcroSeal® packaging improve the product’s stability?
The AcroSeal® technology features a resealable, airtight septum that minimizes exposure to moisture and oxygen, reducing degradation and ensuring consistent concentration over time. This is critical for hygroscopic reagents like HCl.
