Description

1,4-Bis(2-Bromoethyl)Benzene is a versatile and high-purity brominated aromatic building block essential for advanced organic synthesis. Its bifunctional structure, featuring two reactive bromoethyl arms on a para-substituted benzene ring, makes it a critical precursor for constructing complex molecular architectures. This compound is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for applications such as linker chemistry, polymer cross-linking, and the synthesis of liquid crystals.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating bridged or extended molecular structures.
• Agrochemical Synthesis: Used as a precursor in the development of herbicides, fungicides, and other crop protection agents requiring specific aromatic spacers.
• Polymer & Material Science: Acts as a cross-linking agent or monomer in the production of specialty polymers, resins, and advanced materials with tailored properties.
• Liquid Crystal Production: Employed in the synthesis of mesogenic compounds for display technologies due to its rigid central benzene core and flexible terminal bromine groups.
• Organic Synthesis Reagent: Functions as a versatile alkylating agent or linker in multi-step synthetic routes for complex organic molecules in R&D settings.
• Chemical Research: Utilized in academic and industrial laboratories for developing novel synthetic methodologies and exploring new chemical entities.

Quality Control

Our 1,4-Bis(2-Bromoethyl)Benzene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality attributes. Our quality commitment aligns with cGMP principles where applicable, supporting our customers' regulatory and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions. For long-term storage, consider under an inert atmosphere to maintain optimal purity.
