Benzene for UV is a high-purity, low-absorbance solvent designed for ultraviolet (UV) and spectrophotometric applications in pharmaceutical and analytical laboratories, providing a clear medium for accurate optical measurements.
🏭⚗️ Production
Benzene for UV is purified through fractional distillation and filtration to remove peroxides, moisture, and UV-absorbing impurities, then packaged under inert, moisture-controlled conditions to maintain chemical stability and optical clarity.
🔬 Properties
Benzene is a clear, colorless, volatile liquid with a characteristic aromatic odor. It is non-polar, immiscible with water, has a boiling point of ~80.1 °C, and exhibits minimal UV absorbance above 280 nm, making it suitable for UV–Vis spectroscopy of non-polar compounds.
🧪 Applications
Used as a solvent for calibration standards, reference solutions, and assay samples, Benzene dissolves non-polar pharmaceutical compounds and excipients. It is ideal for UV–Vis measurements, solubility studies, and analytical method development requiring high optical purity.
⚠️ Safety
Benzene is highly flammable and carcinogenic. It is toxic if inhaled, ingested, or absorbed through the skin, and prolonged exposure may affect the bone marrow and central nervous system. Handle in a fume hood with gloves, goggles, and protective clothing. Store in tightly sealed containers, away from heat and ignition sources, and dispose of waste according to laboratory safety protocols.
