1. Acts 1-Bromonaphthalene as a core naphthalene intermediate, efficiently synthesizing bromonaphthalene derivatives for high-performance optoelectronic materials and organic semiconductor production.

2. Serves 1-Bromonaphthalene CAS 90-11-9 as a key cross-coupling building block, stably preparing substituted naphthalene compounds for pharmaceutical intermediates and agrochemical manufacturing.

3. Functions as a fine chemical raw material, reliably fabricating specialty solvents and flame retardants with excellent thermal stability for industrial and material applications.

Store 1-Bromonaphthalene CAS 90-11-9 (colorless to pale yellow liquid, density 1.482g/cm³, mp -6.2℃, bp 281℃, flash point 127℃, purity ≥99%, light-sensitive) at 5–30℃ 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 gas mask; avoid skin/eye contact, vapor inhalation and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local brominated naphthalene environmental regulations.

1-Bromonaphthalene CAS 90-11-9 is an industrial brominated aromatic liquid intermediate, not for direct pure-form human contact or ingestion; vapor inhalation causes mild respiratory irritation, and skin contact leads to slight discomfort.

In regulated use, 1-Bromonaphthalene CAS 90-11-9 features high bromine purity and excellent coupling reactivity, good miscibility with organic solvents, stable dark storage performance, and the naphthalene skeleton provides strong π-conjugation for high-yield synthesis of functional aromatic compounds.
