Product Overview
Cyclohexane, 99.5% extra dry, is a high-purity aliphatic solvent designed for critical laboratory applications where moisture contamination is a concern. The AcroSeal® packaging ensures minimal exposure to atmospheric moisture, preserving the solvent’s integrity for extended periods. This grade is particularly valued for its low water content (typically <0.005%), making it ideal for reactions sensitive to trace humidity, such as Grignard formations, lithium-aluminum hydride reductions, and other moisture-excluding processes. The solvent’s narrow boiling range (80.7°C) and high evaporation rate provide consistent performance in chromatographic separations and extractions. Its non-polar nature and compatibility with a wide range of organic compounds further enhance its utility in synthesis and purification workflows. The extra dry specification is achieved through rigorous distillation and molecular sieve treatment, ensuring batch-to-batch reliability. AcroSeal® bottles feature a tamper-evident cap and a PTFE-lined septum for precise dispensing without compromising purity. This product adheres to stringent quality controls, with lot-specific certificates of analysis available for traceability in regulated environments.
FAQs
1. What is the maximum water content in this extra dry cyclohexane?
The water content is guaranteed to be below 0.005% (50 ppm), verified via Karl Fischer titration for each batch.
2. Can this cyclohexane be used with air-sensitive reagents like n-butyllithium?
Yes, the extra dry grade and AcroSeal® packaging minimize moisture and oxygen exposure, making it suitable for air-sensitive reactions.
3. How does AcroSeal® packaging differ from standard bottles?
AcroSeal® bottles incorporate a PTFE-lined septum and a threaded cap with a tamper-evident seal, reducing solvent evaporation and contamination risks.
4. Is this cyclohexane compatible with HPLC or GC analysis?
While primarily designed for synthesis, its high purity (99.5%) and low UV absorbance make it adaptable for certain chromatographic applications after validation.
5. What precautions should be taken during storage to maintain purity?
Store unopened bottles in a cool, dry place away from direct sunlight. Once opened, reseal tightly and use within 6 months for optimal performance.
