Product Overview

1,2-Dichlorobenzene, 98%+ Extra Dry, is a high-purity aromatic solvent designed for demanding laboratory applications where moisture and impurities must be rigorously controlled. The AcroSeal® packaging ensures long-term stability by preventing atmospheric contamination, making it ideal for experiments requiring consistent solvent performance. This grade is meticulously distilled to remove trace water and volatile impurities, delivering a reliable baseline for reactions, separations, and analytical procedures. Its low reactivity and high boiling point (180°C) provide versatility in thermal applications, while the sealed format minimizes handling risks and extends shelf life. The extra-dry specification is critical for moisture-sensitive reactions, such as Grignard formations or lithium-aluminum hydride reductions, where even trace water can compromise yields. The solvent’s refractive index (1.551) and density (1.305 g/mL) are tightly controlled for reproducibility in spectroscopic and density-based protocols. Compatible with most organic solvents, it serves as a non-polar alternative in biphasic systems or as a standalone medium for dissolving hydrophobic compounds. The AcroSeal® cap features a PTFE-lined septum to prevent leakage and evaporation, ensuring the solvent remains uncontaminated until use.

FAQs

1. What is the moisture content in this Extra Dry grade of 1,2-Dichlorobenzene?

The Extra Dry specification guarantees a moisture content of ≤0.005% (50 ppm), verified via Karl Fischer titration to meet stringent lab requirements.

2. Can this solvent be used directly in HPLC or GC applications without further purification?

While the 98%+ purity is suitable for many HPLC and GC applications, we recommend filtering through a 0.22 µm PTFE membrane if particulate-free baseline stability is critical for your instrumentation.

3. How does the AcroSeal® packaging differ from standard glass bottles?

The AcroSeal® system integrates a PTFE-faced septum and a screw cap with a built-in sealant layer, reducing oxygen/moisture ingress by 90% compared to traditional closures, preserving solvent integrity.

4. Is this product compatible with plastic labware like PP or HDPE containers?

1,2-Dichlorobenzene can degrade polyolefins (PP/HDPE) over prolonged contact. Use glass, PTFE, or PFA containers for storage or reactions to avoid leaching or container failure.

5. What alternatives exist if I need a lower-boiling chlorinated solvent?

For applications requiring a lower boiling point, consider dichloromethane (40°C) or chloroform (61°C), though these lack the thermal stability and aromaticity of 1,2-dichlorobenzene.
