2-Acetylnaphthalene is an important naphthalene ketone derivative intermediate widely used in pharmaceutical synthesis, fine chemicals, perfume industry and organic optoelectronic materials. It has a rigid naphthalene ring structure with acetyl functional group, capable of undergoing condensation, reduction, substitution and cyclization reactions to synthesize various high-value downstream compounds. It serves as a core building block for the preparation of anti-inflammatory drugs, analgesics, cardiovascular intermediates and anticancer pharmaceutical raw materials. In fragrance and essence industry, it is used to prepare high-end synthetic spices with unique woody and floral aroma. It is also widely applied in the production of fluorescent brighteners, organic pigments, dye intermediates and photoelectric functional materials. Additionally, it is commonly used in laboratory organic synthetic route design, reaction mechanism research and customized fine chemical intermediate development.

This naphthalene ketone compound has low acute toxicity and mild irritant properties, requiring standardized protective measures during handling and storage. Inhalation of fine crystalline dust may irritate respiratory mucosa, causing throat dryness, cough and slight chest discomfort in poorly ventilated working environments. Direct skin contact may lead to local redness, itching and mild inflammatory reaction; prolonged repeated exposure may cause skin dryness and allergic dermatitis in sensitive individuals. Eye contact can induce conjunctival congestion, burning pain and foreign body sensation, and immediate continuous rinsing with plenty of clean water for at least 15 minutes is required after accidental exposure. Accidental ingestion may trigger mild gastrointestinal symptoms such as nausea and abdominal distension. All operations should be carried out in a well-ventilated fume hood; operators must wear chemical-resistant gloves, safety goggles and dust mask. Store tightly sealed away from light, high temperature and strong oxidizing substances. Waste residues and contaminated packaging must be disposed in accordance with hazardous waste regulations, and arbitrary discharge into water and soil is prohibited to avoid ecological pollution and potential health risks.
