1. Acts 1-bromo-4-fluoro-2-iodobenzene as a multi-halogenated aryl building block, efficiently enabling site-selective cross-coupling (Suzuki, Sonogashira) for synthesizing fluorinated pharmaceutical intermediates and bioactive molecules.

2. Serves 1-bromo-4-fluoro-2-iodobenzene CAS 202865-72-3 as a key fluorinated aromatic intermediate, stably preparing arylboronic esters and alkynyl derivatives for agrochemical and functional material production.

3. Functions as a fine chemical raw material, reliably fabricating fluorinated aromatic polymers with enhanced chemical stability for advanced optoelectronic and material applications.

Store 1-bromo-4-fluoro-2-iodobenzene CAS 202865-72-3 (colorless to pale orange liquid, mp 34-38℃, density 2.21g/cm³, purity ≥98%, light-sensitive) at 5–25℃ in sealed amber glass/HDPE bottles in a cool, dry, dark & well-ventilated area, away from open fire, strong oxidants and direct sunlight. Wear nitrile gloves, safety goggles and organic vapor mask; avoid vapor inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local fluorinated polyhalogenated benzene environmental regulations.

1-bromo-4-fluoro-2-iodobenzene CAS 202865-72-3 is an industrial multi-halogenated 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-bromo-4-fluoro-2-iodobenzene CAS 202865-72-3 features site-selective reactivity (I > Br > F), excellent compatibility with Pd/Cu-catalyzed coupling, good solubility in common organic solvents, stable dark storage, and fluorine substitution enhances molecular stability and bioactivity for high-yield synthesis of fluorinated functional compounds.
