Product Overview
Carbon disulfide (CS₂), 99.9% pure and HPLC-grade, is a highly refined solvent designed for demanding laboratory applications. This colorless, volatile liquid is characterized by its exceptional purity, with minimal trace impurities, making it suitable for high-performance liquid chromatography (HPLC) and other sensitive analytical techniques. Its low viscosity and high solvency power allow for efficient dissolution of nonpolar compounds, while its sharp, ether-like odor serves as a practical indicator of its presence. The solvent’s high volatility ensures rapid evaporation, reducing residue formation in analytical procedures. Stored in airtight, amber glass bottles to prevent degradation from light and moisture, this reagent maintains stability under standard lab conditions. Its chemical inertness toward many organic and inorganic substances further enhances its utility in synthesis and extraction processes. Rigorous quality control ensures batch-to-batch consistency, meeting the stringent requirements of research and industrial laboratories.
FAQs
1. What is the shelf life of HPLC-grade carbon disulfide?
When stored in a tightly sealed container away from heat and light, unopened bottles retain optimal purity for up to 24 months from the date of manufacture.
2. Is this carbon disulfide compatible with plastic containers?
No, it reacts with many plastics and rubber materials. Always use glass or PTFE-lined containers for storage and handling.
3. How does the 99.9% purity compare to technical-grade carbon disulfide?
HPLC-grade (99.9%) has significantly lower levels of sulfur compounds, water, and organic impurities, ensuring reliable results in sensitive applications where technical-grade (typically 99%) may introduce interference.
4. What precautions should be taken during storage?
Store in a cool, well-ventilated area away from ignition sources, oxidizing agents, and direct sunlight. Use explosion-proof refrigeration if storing large quantities.
5. Can this be used as a substitute for chloroform in extractions?
While it shares some solvency properties, carbon disulfide has a lower density and different polarity. Compatibility depends on the specific extraction protocol and target compounds.
