Product Overview

1,2-Dichloroethane 99% AR is a high-purity, colorless solvent widely utilized in laboratory settings for its exceptional dissolving capabilities and stability. This analytical reagent-grade chemical is meticulously refined to ensure minimal impurities, making it ideal for sensitive applications where consistency is critical. With a boiling point of 83.5°C and a density of 1.253 g/mL at 20°C, it offers predictable performance in controlled environments. The solvent exhibits low viscosity and high volatility, facilitating efficient evaporation without residue formation. Its non-hygroscopic nature prevents moisture absorption, maintaining integrity during storage and handling. Compatible with most organic compounds, it serves as an effective medium for extractions, recystallizations, and as a reaction solvent in organic synthesis. The AR-grade certification guarantees adherence to strict quality standards, ensuring reliable results in quantitative analysis and chromatographic techniques. Packaged in leak-proof containers to prevent contamination, this 1,2-Dichloroethane variant meets the exacting requirements of modern laboratories while adhering to safety protocols for halogenated hydrocarbons.

FAQs

1. What is the shelf life of 1,2-Dichloroethane 99% AR when stored properly?

When stored in a tightly sealed container away from direct sunlight and moisture at room temperature, the shelf life is typically 24 months from the date of manufacture. Regularly check for any signs of degradation like color change or sediment formation.

2. Can this solvent be used with glassware, or does it require special containers?

1,2-Dichloroethane is compatible with most borosilicate glassware commonly used in labs. However, prolonged exposure may affect certain plastics and rubber stoppers. For long-term storage, use containers with PTFE-lined caps to prevent potential corrosion of metal components.

3. What safety precautions should be taken while handling this chemical?

Always handle in a well-ventilated fume hood wearing appropriate PPE including nitrile gloves, safety goggles, and a lab coat. Avoid inhalation of vapors and skin contact. The chemical is classified as a potential carcinogen, so follow standard operating procedures for halogenated solvents.

4. How does the AR grade differ from technical or industrial grades?

AR grade undergoes rigorous purification processes to remove trace impurities, heavy metals, and residual moisture that could interfere with analytical results. Technical grades may contain higher levels of contaminants (up to 1-2%) and are generally used for non-critical applications where purity is less critical.

5. What is the typical evaporation rate compared to other common solvents?

The evaporation rate of 1,2-Dichloroethane is relatively moderate compared to highly volatile solvents like diethyl ether but faster than less volatile options like chloroform. Under standard lab conditions, it evaporates completely within 1-2 hours when spread in a thin layer, making it suitable for applications requiring controlled solvent removal.
