Store 2-Bromo-7-Chlorofluorene CAS 99586-26-2 (white crystalline powder, mp 142-145℃, density 1.52g/cm³, purity ≥98%, light-sensitive) at 5–25℃ in sealed amber glass/HDPE drums in a cool, dry, dark & well-ventilated area, away from open fire, strong oxidants and direct sunlight. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local halogenated fluorene fine chemical environmental regulations (no discharge to water).

2-Bromo-7-Chlorofluorene CAS 99586-26-2 is an industrial bromo-chloro fluorene heterocyclic intermediate, not for direct pure-form human contact and forbidden to release into water; undiluted dust may cause mild respiratory/skin irritation, and 2-Bromo-7-Chlorofluorene CAS 99586-26-2 has potential aquatic toxicity with adverse environmental impacts. In regulated use, it features differential halogen reactivity (C-Br＞C-Cl) for precise site modification, high chemical purity, good solubility in organic solvents, stable dark storage performance, and the fluorene skeleton ensures strong π-conjugation for optoelectronic material synthesis.
