Description

(2-Bromo-1,4-Phenylene)Dimethanol is a versatile brominated aromatic diol derivative, serving as a critical bifunctional building block in advanced organic synthesis. Its molecular structure, featuring both a bromine substituent and two hydroxymethyl groups, makes it an invaluable precursor for constructing complex molecules and functional materials. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require high-purity intermediates for developing active ingredients and novel polymers.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a brominated aromatic core with pendant functional groups.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and other crop protection agents where its structure imparts specific biological activity.
• Liquid Crystal & OLED Materials: Serves as a core building block for creating advanced organic electronic materials, including liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).
• Polymer & Resin Modifier: Acts as a monomer or cross-linking agent in the production of specialty polymers, epoxy resins, and high-performance coatings to enhance thermal or mechanical properties.
• Ligand & Catalyst Preparation: Utilized in organometallic chemistry to synthesize chelating ligands for metal catalysts used in asymmetric synthesis and coupling reactions.
• Organic Synthesis Reagent: Employed in various name reactions (e.g., Suzuki, Heck cross-coupling) as a versatile electrophile or for further functionalization of the hydroxymethyl groups.

Quality Control

Our (2-Bromo-1,4-Phenylene)Dimethanol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure high purity and batch-to-batch consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting identity, assay, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated synthesis pathways.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
