Product Overview
Toluene USP is a high-purity aromatic hydrocarbon solvent widely used in laboratory and industrial applications due to its excellent solvency properties. This clear, colorless liquid meets United States Pharmacopeia (USP) standards, ensuring consistent quality with a minimum purity of 99.5%. Its low moisture content (≤0.05%) and non-corrosive nature make it ideal for sensitive chemical processes. The solvent has a characteristic aromatic odor and a boiling point of 110.6°C, providing a stable working range for various procedures. Toluene USP is miscible with most organic solvents but immiscible with water, offering selective solubility for extraction processes. Its refractive index of 1.496-1.499 at 20°C allows for precise optical measurements. The product comes in a leak-proof HDPE bottle with a tamper-evident seal, ensuring safe storage and handling. Each batch undergoes rigorous quality control testing for heavy metals, residual solvents, and other impurities to meet USP specifications. The solvent’s low viscosity and rapid evaporation rate make it particularly useful in thin-layer chromatography and sample preparation applications.
FAQs
1. What is the shelf life of Toluene USP when stored properly?
When stored in a tightly sealed container away from heat and ignition sources, Toluene USP maintains its specified purity for 24 months from the date of manufacture. The container should be kept in a well-ventilated area below 30°C.
2. Is this Toluene USP grade compatible with plastic containers for long-term storage?
While Toluene USP can be temporarily stored in HDPE containers like the one provided, it’s not recommended for long-term storage in most plastics as it may cause degradation. For extended storage, glass containers with PTFE-lined caps are preferable.
3. What are the key differences between Toluene USP and laboratory-grade toluene?
Toluene USP undergoes more stringent purity testing, particularly for residual impurities and heavy metals, making it suitable for pharmaceutical and food-related applications. Laboratory-grade toluene typically has slightly lower purity standards and may contain trace impurities.
4. Can this Toluene USP be used in UV-Vis spectroscopy applications?
Yes, Toluene USP is suitable for UV-Vis spectroscopy as it has excellent transparency in the UV range. Its low absorbance at wavelengths above 280 nm makes it particularly useful for spectroscopic analysis of organic compounds.
5. What safety precautions should be taken when handling Toluene USP?
Always handle Toluene USP in a fume hood or well-ventilated area. Use nitrile gloves, safety goggles, and a lab coat. Avoid inhalation of vapors and skin contact. Keep away from open flames and static discharge sources as toluene is highly flammable.
