Description

1-Bromo-2-Isopropenyl-Benzene is a versatile brominated aromatic building block characterized by its reactive isopropenyl group. This compound is valued for its role as a key intermediate in advanced organic synthesis, enabling the introduction of both aromatic bromine and a polymerizable alkene functionality. It is primarily sought after by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a bromoarene moiety for further cross-coupling reactions.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and insecticides where the bromine atom facilitates subsequent functionalization.
• Specialty Polymer & Resin Monomer: The isopropenyl group allows for polymerization, making it suitable for creating novel styrenic copolymers, coatings, and adhesives with specific properties.
• Ligand & Catalyst Preparation: Employed in the synthesis of specialized phosphine or N-heterocyclic carbene (NHC) ligands for transition metal catalysis.
• Material Science Research: Acts as a building block for organic electronic materials, such as those used in OLEDs or conductive polymers.
• Custom Chemical Synthesis: Utilized by fine chemical manufacturers for contract research and production of bespoke compounds for various industrial applications.

Quality Control

Our 1-Bromo-2-Isopropenyl-Benzene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Keep away from heat, sparks, and open flame.
