Toluene for UV is a high-purity, low-absorbance solvent specifically refined for ultraviolet (UV) and spectrophotometric applications, ensuring accurate and reproducible optical measurements.

🏭⚗️ Production
Toluene for UV is obtained through fractional distillation and advanced purification processes to remove aromatic impurities, moisture, and peroxides that may interfere with UV absorbance. The solvent is filtered and packaged in amber, moisture-resistant containers under inert conditions to preserve optical clarity and chemical stability.

🔬 Properties
Toluene is a clear, colorless liquid with a characteristic aromatic odor, low density, and high volatility. It exhibits excellent transparency in the UV region, with minimal absorbance above 285 nm. Non-polar and immiscible with water, toluene is an ideal solvent for non-polar compounds in spectrophotometric and photometric analyses.

🧪 Applications
Toluene is used as a solvent and reference medium in UV and visible spectroscopy. It provides stable baselines and consistent absorbance measurements for calibration and analytical quantification. It is commonly used for dissolving non-polar organic analytes, preparing standard solutions, and performing absorbance and transmission studies where high optical purity is essential.

⚠️ Safety
Toluene is flammable and harmful if inhaled or absorbed through the skin. It should be handled in a well-ventilated area or fume hood with gloves, protective eyewear, and lab coats. Containers must be stored tightly sealed, away from heat, sparks, and strong oxidizers. Waste and residues should be disposed of according to laboratory hazardous waste protocols.
