Product Overview

N,N-Dimethylacetamide (DMAc), 99.5% extra dry, is a high-purity polar aprotic solvent processed over molecular sieves to achieve ultra-low moisture content. The AcroSeal® packaging technology ensures long-term stability by preventing atmospheric moisture ingress, making it ideal for applications requiring anhydrous conditions. This grade is particularly valued for its ability to dissolve a wide range of organic and inorganic compounds while maintaining chemical stability. The solvent’s high boiling point (166°C) and low volatility reduce evaporation losses during prolonged reactions. Its miscibility with water and most organic solvents enhances versatility in formulation work. The extra dry specification eliminates the need for additional drying steps, saving time in laboratory workflows. The product meets rigorous quality standards with GC analysis confirming 99.5% minimum purity. Each batch undergoes strict quality control to ensure consistent performance in critical applications.

FAQs

1. What is the maximum water content in this extra dry DMAc?

The molecular sieve drying process reduces water content to typically less than 50 ppm, though exact specifications are provided with each batch’s certificate of analysis.

2. Can this DMAc be used directly without further purification?

Yes, the extra dry grade is designed for direct use in moisture-sensitive applications without requiring additional drying procedures.

3. How does AcroSeal® packaging differ from standard bottles?

AcroSeal® packaging incorporates a specialized septum and cap system that creates a vapor-tight seal, preventing both moisture ingress and solvent evaporation.

4. What is the typical shelf life of this product?

When stored unopened in its original AcroSeal® packaging at room temperature, the product maintains its specifications for at least 24 months from the date of manufacture.

5. Are there any special storage requirements for this solvent?

Store in a cool, dry place away from direct sunlight and incompatible materials. Keep containers tightly sealed when not in use to maintain the extra dry specification.
