Product Overview

N,N-Dimethylacetamide (DMAc) at 99.5% purity in Extra Dry grade is a high-performance polar aprotic solvent designed for critical laboratory applications where moisture control is paramount. The AcroSeal® packaging ensures minimal exposure to atmospheric moisture, preserving the solvent’s integrity for extended shelf life. This grade of DMAc is characterized by its low water content (<50 ppm), making it particularly suitable for reactions sensitive to hydrolysis or where trace water could compromise yield or selectivity. Its high boiling point (166°C) and excellent solvating power for a wide range of organic and inorganic compounds make it a versatile choice for synthesis, purification, and formulation processes. The solvent’s low volatility reduces evaporation losses during prolonged reactions, while its miscibility with water and most organic solvents enhances its utility in multi-component systems. The Extra Dry specification is achieved through rigorous purification and packaging under inert conditions, ensuring consistent performance in demanding applications.

FAQs

1. What is the typical moisture content in this Extra Dry grade of N,N-Dimethylacetamide?

The moisture content is maintained below 50 ppm, verified through Karl Fischer titration to meet the Extra Dry specification.

2. Can this DMAc be used directly in air-sensitive reactions without further drying?

While the AcroSeal® packaging significantly reduces moisture ingress, for ultra-sensitive applications, additional drying with molecular sieves may be recommended.

3. What materials are compatible with long-term storage of this solvent?

Glass or PTFE-lined containers are ideal for storage. Avoid prolonged contact with metals like aluminum or copper to prevent potential contamination.

4. How does the AcroSeal® packaging differ from standard bottles for solvents?

The AcroSeal® system incorporates a specialized septum and cap design that minimizes air exposure during dispensing, reducing moisture absorption and solvent degradation.

5. Are there any stabilization additives in this grade of DMAc?

This product is additive-free to maintain maximum purity for analytical and synthetic applications where trace contaminants could interfere with results.
