1. Acts 2 4′-Dibromobiphenyl as a core dibrominated biphenyl intermediate, efficiently synthesizing functionalized biphenyl derivatives for high-performance organic optoelectronic and semiconductor material manufacturing.

2. Serves 2 4′-Dibromobiphenyl CAS 49602-91-7 as a key cross-coupling building block, stably preparing substituted biphenyl compounds for pharmaceutical intermediates and agrochemical R&D production.

3. Functions as a fine chemical raw material, reliably fabricating flame-retardant polymers with excellent thermal stability for advanced industrial material applications.

Store 2 4′-Dibromobiphenyl CAS 49602-91-7 (off-white crystalline powder, mp 80-82℃, density 1.72g/cm³, bp 345℃, purity ≥98%, air-stable) at 5–25℃ in sealed HDPE/amber glass drums in a cool, dry, well-ventilated area, away from open fire, strong oxidants and halogenated reagents. 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 brominated aromatic regulations (ban direct water discharge).

2 4′-Dibromobiphenyl CAS 49602-91-7 is an industrial brominated aromatic intermediate with aquatic toxicity, strictly forbidden to release into water bodies; undiluted dust causes mild respiratory irritation.

In regulated use, 2 4′-Dibromobiphenyl CAS 49602-91-7 features high regioselectivity in C–Br bond reactions, good solubility in aromatic/halogenated solvents, excellent thermal stability during processing, and the asymmetric dibromo structure enables precise synthesis of functional biphenyl products with high yield.
