Product Overview
Benzene 99.9% GC is a high-purity aromatic hydrocarbon widely used as a non-polar solvent in laboratory settings. This colorless, highly volatile liquid is characterized by its distinct aromatic odor and excellent solvency properties, making it indispensable for applications requiring precise chemical reactions. With a minimum purity of 99.9% as confirmed by gas chromatography (GC), this grade ensures minimal impurities, guaranteeing reliable and reproducible results in analytical procedures. Its low polarity and ability to dissolve a wide range of organic compounds make it a preferred choice for extraction processes, thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). The product is packaged in amber glass bottles to prevent photodegradation, preserving its stability during storage. As a versatile solvent, it also serves as a key reagent in organic synthesis, particularly in Friedel-Crafts alkylation and sulfonation reactions. Proper handling is essential due to its flammable nature and potential health hazards, requiring storage in a cool, well-ventilated area away from ignition sources. This grade meets stringent quality standards, ensuring consistency for critical laboratory applications.
FAQs
1. What is the shelf life of Benzene 99.9% GC when stored properly?
When stored in a tightly sealed container away from light, heat, and moisture, Benzene 99.9% GC typically retains its purity for up to 24 months from the date of manufacture. Regularly check for signs of contamination or evaporation before use.
2. Is this grade of benzene compatible with plastic containers for short-term storage?
Benzene can degrade certain plastics, including polystyrene and polyethylene, leading to contamination. For short-term storage, use glass containers or HDPE bottles specifically rated for aromatic hydrocarbons to maintain purity.
3. Can Benzene 99.9% GC be used as a substitute for toluene in specific applications?
While benzene and toluene share similar solvent properties, benzene’s higher toxicity and volatility may limit its suitability as a direct substitute. Evaluate the application’s safety requirements and solvent compatibility before substitution, as toluene is generally preferred for less hazardous processes.
4. What precautions should be taken when handling Benzene 99.9% GC in a lab?
Always handle benzene in a fume hood with proper ventilation, wearing nitrile gloves, safety goggles, and a lab coat. Avoid inhalation or skin contact, as benzene is a known carcinogen. Use spark-proof tools and store away from oxidizing agents to prevent fire hazards.
5. How does the GC purity certification differ from other purity grades like ACS or reagent grade?
GC (Gas Chromatography) purity certification specifically indicates that the product has been tested and confirmed to contain ≥99.9% benzene with minimal detectable impurities via GC analysis. ACS or reagent grades may have broader purity criteria, including limits on heavy metals or residual solvents, but GC-grade focuses solely on chromatographic purity.
