Product Name – Chlorobenzene, 99.5%, Extra Dry over Molecular Sieve, AcroSeal® Quantity/Pack Size – 1LT, 100ML Form – Liquid Grade – Extra Dry (99.5%) Application – Solvent for moisture-sensitive reactions, organic synthesis

Product Overview

Chlorobenzene, 99.5% purity with extra dry properties, is a high-grade solvent processed over molecular sieves to ensure minimal moisture content. This AcroSeal® variant is packaged under inert conditions to maintain stability and prevent contamination, making it ideal for applications requiring anhydrous conditions. The solvent’s low water content (<50 ppm) ensures reliability in moisture-sensitive reactions, while its sealed packaging preserves purity during storage and handling. With a boiling point of 131°C and density of 1.106 g/mL, it serves as a versatile reagent in organic synthesis, particularly in Friedel-Crafts reactions and as a solvent for electrophilic substitutions. The AcroSeal® technology guarantees long-term stability, reducing the risk of degradation or moisture absorption over time. Compatible with most glass and PTFE labware, this chlorobenzene variant is a staple in research and analytical laboratories where precision and consistency are critical.

FAQs

1. What does “extra dry over molecular sieve” mean for chlorobenzene?

Extra dry indicates the solvent has been treated with molecular sieves to reduce moisture content to trace levels, typically below 50 ppm. This ensures suitability for reactions where water interference is detrimental.

2. Can this chlorobenzene be used with standard glassware?

Yes, it is compatible with borosilicate glass and PTFE-lined containers. Avoid prolonged storage in plastic or rubber-sealed vessels, as these may degrade or leach contaminants.

3. How should this product be stored to maintain its dryness?

Store in a tightly sealed AcroSeal® bottle under inert gas (if opened) at room temperature. Keep away from direct sunlight and moisture sources like humidifiers or open water baths.

4. What alternatives exist if this specific grade is unavailable?

For less moisture-sensitive applications, reagent-grade chlorobenzene (99% purity) can be used, though drying with molecular sieves may be required prior to use.

5. Is this chlorobenzene suitable for NMR spectroscopy?

While it can be used as a solvent, deuterated chlorobenzene (C6D5Cl) is preferred for NMR due to its lack of proton signals, which simplifies spectral interpretation.
