Product Overview
Diethylene glycol AR is a high-purity, colorless, and hygroscopic liquid widely used in laboratory settings for its exceptional solvent properties. This analytical reagent (AR) grade ensures minimal impurities, making it ideal for precise applications where consistency and reliability are critical. With a molecular formula of C4H10O3, it exhibits excellent miscibility with water, alcohols, and many organic solvents, providing versatility in various chemical processes. Its low volatility and high boiling point (245°C) contribute to stable performance under controlled conditions. Diethylene glycol AR is particularly valued for its role in chemical synthesis, as a humectant, and in the preparation of specialty formulations. The product is rigorously tested to meet strict quality standards, ensuring reproducibility in experimental and analytical workflows. Its non-corrosive nature and compatibility with a wide range of materials further enhance its utility in diverse laboratory environments. Proper storage in tightly sealed containers is recommended to maintain its integrity and prevent moisture absorption.
FAQs
1. What is the shelf life of diethylene glycol AR?
When stored in a cool, dry place in its original sealed container, diethylene glycol AR typically has a shelf life of 2-3 years.
2. Is this product compatible with glass containers?
Yes, diethylene glycol AR is compatible with glass containers and does not react adversely with standard laboratory glassware.
3. Can diethylene glycol AR be used as a substitute for ethylene glycol?
While both are glycols, diethylene glycol AR has different physical properties and applications, so direct substitution is not recommended without validation.
4. What precautions should be taken during handling?
Wear appropriate personal protective equipment (PPE) such as gloves and goggles, and ensure adequate ventilation when handling diethylene glycol AR.
5. How should spills of diethylene glycol AR be managed?
Contain the spill with absorbent materials, collect in a suitable container, and dispose of according to local chemical waste regulations.
