| About the compound: | O-xylene, or ortho-xylene, is a chemical compound with the molecular formula C8H10. This colorless, slightly oily liquid is a constitutional isomer of the other xylene compounds, meta-xylene and para-xylene. It is typically derived from the distillation of petroleum and is primarily used in the production of phthalic anhydride, which is a precursor to many dyes, plastics, and other chemicals. The compound has a boiling point ranging between 143-145 °C and exhibits a characteristic sweet, aromatic odor. O-xylene is slightly less dense than water, with a density of about 0.88 g/mL at 20 °C. It is also known for its moderate volatility and flammability, making it an important solvent in the chemical industry. O-xylene's toxicity is relatively low compared to other industrial compounds, but it can have narcotic effects at high concentrations. Its oral LD50 for rats is reported as 4300 mg/kg, indicating moderate acute toxicity. Safety measures are essential when handling o-xylene due to its flammable nature and potential health effects from prolonged exposure. References • National Institute of Standards and Technology.

SKIN: Rinse affected skin with water, wash with soap, and seek medical help if irritation occurs. INHALATION: Leave contaminated area, breathe fresh air, and seek medical help if symptoms arise. Use proper respiratory protection. INGESTION: Do not induce vomiting. Give water if conscious and seek medical help. If unconscious, ensure open airway and transport to hospital without inducing vomiting.
