2-Bromofluorene is core aromatic intermediate widely used in OLED luminescent material, organic photoelectric semiconductor and fine chemical synthesis industry, owning rigid fluorene conjugated skeleton structure and reactive bromine substitution site for coupling reactions such as Suzuki, Buchwald and Heck reaction. In optoelectronic field, it is fundamental raw material to synthesize blue light-emitting OLED monomers, hole transport materials and conjugated polymer for organic solar cell, modifying molecular conjugation length to adjust luminous efficiency and thermal stability of finished optoelectronic products. For pharmaceutical intermediate manufacture, it takes part in aromatic ring derivatization to prepare anti-cancer and nervous system drug intermediates via lithiation and substitution reaction. It also serves as starting material for synthesizing carbazole-terminated oligofluorene and liquid crystal monomer with high heat resistance. High-purity grade is adopted for organic synthesis research in university chemical laboratory and new material R&D institute. Standard export package:25kg iron drum with inner PE liner; lab sample packed in 1kg/5kg sealed plastic bottle for global electronic chemical buyers.

GHS:H315,H319,H335；Signal Word:Warning Organic irritant solid, crystalline dust irritates skin, eye and respiratory mucous membrane noticeably. Direct skin contact triggers red rash and pruritus; immediately remove contaminated clothing and rinse affected skin with continuous running tap water over 15 minutes after exposure. Powder splashed into eyes causes conjunctiva congestion and stabbing pain, sustain eye washing with purified water no less than 15min and seek medical care if discomfort persists. Inhalation of fine dust induces dry throat and intermittent cough; all weighing and feeding operations must be completed in ventilated fume cabinet with nitrile resistant gloves, anti-splash safety goggles and particulate respirator. Store in cool dry airtight warehouse, segregated from strong oxidants, alkaline chemicals and food raw materials. Waste solid and production filtrate belong to general organic hazardous waste, delivered to qualified professional disposal company following local environmental regulation, forbidden direct discharge into sewer or open soil.
