Product Overview
N,N-Dimethylacetamide (DMAc) AR is a high-purity, polar aprotic solvent widely used in laboratory settings for its excellent solvency properties. This analytical reagent grade solvent is characterized by its low moisture content (<0.1%), making it ideal for moisture-sensitive reactions. DMAc exhibits a high boiling point (166°C) and strong solvating power for a wide range of organic and inorganic compounds, including polymers like polyimides and polyamides. Its low volatility and thermal stability enhance its utility in prolonged reactions. The solvent's ability to dissolve both polar and non-polar substances makes it particularly valuable in synthesis applications. DMAc AR undergoes rigorous purification processes to ensure minimal impurities, with typical specifications including ≤0.005% water content and ≤0.001% heavy metals. The solvent's refractive index (1.436-1.438) and density (0.937 g/mL) remain consistent across batches, ensuring reproducible results in analytical applications.
FAQs
1. What is the typical shelf life of N,N-Dimethylacetamide AR?
When stored properly in tightly sealed original containers at room temperature, N,N-Dimethylacetamide AR maintains its specifications for 24 months from the date of manufacture.
2. How should this solvent be stored to maintain purity?
Store in a cool, dry place away from direct sunlight and incompatible substances. Keep containers tightly closed when not in use to prevent moisture absorption.
3. What safety precautions should be taken when handling DMAc?
Use in a well-ventilated area or fume hood. Wear appropriate PPE including chemical-resistant gloves, safety goggles, and lab coat. Avoid skin contact and inhalation of vapors.
4. Is this grade suitable for HPLC applications?
While DMAc AR is highly pure, for HPLC applications we recommend our HPLC-grade solvents which undergo additional purification steps specifically for chromatographic techniques.
5. What’s the difference between AR grade and technical grade DMAc?
AR grade undergoes more rigorous purification with stricter specifications for impurities, moisture content, and heavy metals compared to technical grade, making it suitable for analytical applications.
