Product Overview
Ethylbenzene, 99.8% anhydrous, is a high-purity aromatic hydrocarbon designed for demanding laboratory applications where moisture sensitivity is a critical concern. Packaged under the AcroSeal® system, this solvent ensures minimal exposure to atmospheric moisture, preserving its integrity for extended periods. The 99.8% purity level makes it suitable for precise analytical techniques, including gas chromatography and high-performance liquid chromatography (HPLC), where even trace impurities can compromise results. Its anhydrous nature eliminates water interference in reactions, making it ideal for organic synthesis, particularly in Grignard reactions, Friedel-Crafts alkylations, and other moisture-sensitive processes. The compound’s low peroxide formation tendency enhances shelf stability, while its consistent boiling point (136°C) ensures reproducible distillation and separation processes. The AcroSeal® packaging features a tamper-evident seal and a resealable cap, reducing contamination risks during repeated use. This grade of ethylbenzene is also compatible with most laboratory glassware and polymeric materials, minimizing leaching concerns. For applications requiring strict adherence to analytical standards, this product meets or exceeds ACS and Reagent Grade specifications, providing reliable baseline data for comparative studies.
FAQs
1. What is the maximum allowable moisture content in this anhydrous ethylbenzene?
The AcroSeal® packaging ensures moisture content remains below 0.005% (50 ppm), verified through Karl Fischer titration upon dispatch.
2. Can this ethylbenzene be used as a substitute for toluene in polymerization reactions?
While structurally similar, ethylbenzene has a higher boiling point and different steric effects, which may alter reaction kinetics compared to toluene.
3. How does the AcroSeal® packaging prevent contamination during storage?
The system uses a dual-layer seal with an inner PTFE-faced septum and an outer polypropylene cap, creating an airtight barrier against moisture and oxygen ingress.
4. What precautions should be taken when handling this solvent in a fume hood?
Despite its low volatility, maintain airflow at ≥0.5 m/s, use spark-proof equipment, and avoid open flames due to its flammability (flash point 15°C).
5. Is this product compatible with standard HPLC mobile phase preparations?
Yes, its UV cutoff (260 nm) and low particulate count (0.5 µm) make it suitable for gradient HPLC systems without additional filtration.
