Description

3,5-Dibromo-4-Chlorophenol is a halogenated phenolic compound that serves as a versatile and highly reactive chemical intermediate. Its value lies in its ability to introduce both bromine and chlorine substituents onto a phenolic core, enabling the synthesis of more complex molecules with tailored properties. This compound is primarily needed by manufacturers in the agrochemical and pharmaceutical industries for the development of active ingredients, as well as by researchers in material science for creating specialized polymers and flame retardants.

Application

• Agrochemical Intermediate: A key building block in the synthesis of advanced herbicides, fungicides, and pesticides, where its halogen atoms contribute to biological activity and environmental persistence.
• Pharmaceutical Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), particularly in creating molecules with antimicrobial or anti-inflammatory properties.
• Polymer & Material Science: Acts as a monomer or additive in the production of specialty polymers, resins, and flame-retardant materials.
• Chemical Research & Development: Serves as a standard or reagent in organic synthesis laboratories for introducing halogenated phenolic groups into target molecules.
• Dye & Pigment Manufacturing: Utilized as a precursor in the synthesis of certain halogenated dyes and organic pigments.

Quality Control

Our 3,5-Dibromo-4-Chlorophenol is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet the high standards required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically ≥97% by HPLC), physical characteristics, and impurity profiles is provided with each shipment and is available upon request.

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 heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in a dark place.
