Description

2-Bromostyrene is a versatile halogenated styrene derivative, serving as a crucial building block in advanced organic synthesis. Its reactive vinyl and bromo functionalities make it an essential intermediate for constructing complex molecular architectures. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce bromine and styrenyl motifs into target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring bromoaryl or styrenyl components.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides where the bromostyrene unit imparts specific biological activity.
• Polymer & Material Science: Serves as a monomer or co-monomer for creating specialty polymers, including functionalized polystyrene derivatives and high-performance resins with modified thermal or optical properties.
• Organic Synthesis Building Block: Employed in cross-coupling reactions (e.g., Suzuki, Heck), polymerization initiators, and as a substrate for further functionalization in fine chemical production.
• Liquid Crystal & OLED Materials: A valuable starting material for synthesizing organic electronic materials and liquid crystal compounds due to its planar aromatic structure and halogen substituent.
• Research & Development: Essential reagent in academic and industrial R&D labs for exploring new synthetic methodologies and developing novel chemical entities.

Quality Control

Our 2-Bromostyrene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. Due to its light-sensitive nature and organic solvent compatibility, ensure containers are kept sealed when not in use to prevent evaporation and degradation.
