1. Acts 1-Bromo-4-fluoronaphthalene CAS 341-41-3 as a key halogenated naphthalene intermediate, efficiently synthesizing fluoro-bromo naphthalene derivatives for high-performance optoelectronic and pharmaceutical material production.

2. Serves 1-Bromo-4-fluoronaphthalene as a core building block in organic synthesis, stably preparing substituted naphthalene compounds for agrochemicals and functional aromatic fine chemicals manufacturing.

3. Functions as a fine chemical raw material, reliably fabricating conjugated polymers and liquid crystal materials with excellent thermal stability for advanced material applications.

Store 1-Bromo-4-fluoronaphthalene CAS 341-41-3 (pale yellow crystalline powder, mp 39-42℃, density 1.62g/cm³, bp 275℃, 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 naphthalene environmental regulations.

1-Bromo-4-fluoronaphthalene CAS 341-41-3 is an industrial halogenated naphthalene intermediate, not for direct pure-form human contact or ingestion; undiluted dust may cause mild respiratory/skin irritation, and high-temperature heating releases toxic halogenated fumes.

In regulated use, 1-Bromo-4-fluoronaphthalene features differential halogen reactivity (C-Br＞C-F) for site-specific modification, high chemical purity, good solubility in organic solvents, stable properties in dark storage, and the naphthalene skeleton ensures excellent π-conjugation for optoelectronic material synthesis.
