Product Overview

N,N-Dimethyl Formamide (DMF) 99.8% PRA is a high-purity, polar aprotic solvent widely used in laboratory settings for its exceptional solvating properties. This pro-analysis grade DMF is meticulously purified to ensure minimal impurities, making it suitable for critical applications where consistency and reliability are paramount. Its low volatility and high boiling point (153°C) provide stability during prolonged reactions, while its miscibility with water and most organic solvents enhances versatility in complex formulations. The 99.8% purity level guarantees reproducible results in synthesis, chromatography, and analytical procedures. DMF’s ability to dissolve both polar and nonpolar compounds makes it indispensable in peptide synthesis, polymer chemistry, and pharmaceutical intermediate production. This grade is particularly valued for its low water content (<0.05%), which prevents unwanted side reactions in moisture-sensitive processes. The solvent’s transparency in UV-Vis spectroscopy further extends its utility in analytical laboratories. Packaged in high-density polyethylene bottles to prevent contamination, this DMF maintains its integrity during storage and handling.

FAQs

1. What is the typical shelf life of N,N-Dimethyl Formamide 99.8% PRA when stored properly?

When stored in tightly sealed original containers at room temperature away from moisture and direct sunlight, this grade of DMF maintains its specified purity for up to 24 months from the date of manufacture.

2. Can this DMF be used as a substitute for DMSO in cell culture applications?

While both are polar aprotic solvents, this PRA-grade DMF is not recommended for cell culture due to its higher toxicity profile compared to DMSO. It’s primarily designed for chemical synthesis and analytical applications.

3. What precautions should be taken when handling N,N-Dimethyl Formamide?

Always use in a well-ventilated fume hood with appropriate PPE including nitrile gloves and safety goggles. Avoid skin contact as DMF can be absorbed through the skin and may cause liver damage with prolonged exposure.

4. How does the PRA grade differ from technical grade DMF?

The PRA grade undergoes additional purification steps to achieve 99.8% purity with strictly controlled impurities, while technical grade typically contains higher levels of water and organic contaminants, making it unsuitable for analytical work.

5. What is the recommended disposal method for unused DMF?

Collect waste DMF in designated solvent waste containers and dispose through licensed chemical waste handlers. Never pour down drains or mix with other solvents without proper authorization.
