Description

Phosphoric Acid 4-Bromophenyl Ester is an organophosphorus compound that serves as a versatile chemical intermediate. Its value lies in its brominated aromatic structure, which provides a reactive site for further functionalization in complex synthesis. This product is primarily needed by R&D laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring a bromophenol moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the bromophenyl group is integral to biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for phosphonate and phosphate-based ligands used in metal catalysis and coordination chemistry.
• Flame Retardant Development: Acts as an intermediate in the creation of organophosphate-based flame retardants for polymers and textiles.
• Polymer Modification: Employed to introduce phosphate groups into polymer chains to alter properties like adhesion, flame resistance, or biocompatibility.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our Phosphoric Acid 4-Bromophenyl Ester is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics are provided and available upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
