Product Overview
This 7N ammonia solution in methanol is a high-purity reagent designed for applications requiring precise ammonia concentration without water interference. The AcroSeal® packaging ensures maximum protection against moisture and atmospheric contamination, maintaining the solution’s integrity during storage and handling. With a nominal concentration of 7N (approximately 12.25% w/w), this reagent provides a consistent ammonia source for chemical transformations where methanol serves as both solvent and reactant. The solution is particularly valuable in organic synthesis protocols where anhydrous conditions are critical, as methanol’s hygroscopic nature helps maintain a water-free environment. Each batch undergoes rigorous quality control to ensure minimal impurities, with trace metal and non-volatile residue levels kept below standard thresholds. The amber glass packaging with PTFE-lined caps prevents degradation from light exposure while maintaining chemical stability. This reagent is compatible with most organic solvents but should be stored under inert atmosphere when not in use to prevent ammonia loss.
FAQs
1. What is the exact ammonia concentration in this solution?
The solution is approximately 7N, which corresponds to about 12.25% w/w ammonia in methanol. The exact concentration is provided on the certificate of analysis for each batch.
2. Can this solution be used directly for GC-MS derivatization?
Yes, this 7N ammonia in methanol solution is suitable for GC-MS derivatization procedures, particularly for compounds requiring methylation or amination reactions under anhydrous conditions.
3. What precautions should be taken when handling this solution?
Always handle in a fume hood due to ammonia’s pungent and corrosive nature. Use chemical-resistant gloves and eye protection, as methanol is flammable and the solution can cause skin irritation.
4. How does AcroSeal® packaging benefit this product?
The AcroSeal® packaging features a special barrier that minimizes moisture ingress and ammonia evaporation, extending shelf life and maintaining concentration accuracy for longer periods.
5. What’s the typical shelf life of this solution when stored properly?
When stored unopened in its original packaging at room temperature, the solution maintains its specified concentration for at least 24 months from the date of manufacture.
