Chrysene is a typical polycyclic aromatic hydrocarbon with stable aromatic structure and unique optical properties. It is mainly applied as a research chemical and organic synthesis intermediate in chemical laboratories and fine chemical industries. It serves as a core raw material for synthesizing functional dyes, fluorescent materials and photoelectric compounds, and is widely used in the research of organic luminescent devices and photosensitive materials. In environmental monitoring, it acts as a standard reference substance for detecting polycyclic aromatic hydrocarbon pollutants in water, soil and air samples. It is also used in the study of organic reaction mechanism and molecular structure analysis. Besides, it is adopted in the preparation of high-temperature resistant organic materials and chemical additives. Due to its special molecular characteristics, chrysene plays an important role in academic research, environmental analysis and the development of new functional organic materials.

GHS Classification: Carcinogenicity (Category 2), Skin Irritation (Category 2), Eye Irritation (Category 2A) This substance is suspected to cause cancer after long-term exposure. Direct skin contact will lead to redness, itching and mild inflammation, while contact with eyes causes stinging, tearing and conjunctival irritation. Inhalation of dust may irritate the respiratory tract and trigger cough and throat discomfort. Accidental ingestion may cause gastrointestinal disorders such as nausea and abdominal pain. Operators must work in a fume hood, wearing dust-proof masks, chemical-resistant gloves and safety goggles. Avoid long-term exposure and repeated contact. Once contacted with skin or eyes, rinse thoroughly with plenty of running water for at least 15 minutes and seek medical treatment in time. Store tightly sealed separately from food and oxidizing agents. Dispose of waste materials strictly in accordance with hazardous waste regulations to prevent pollution to water and soil environment.
