Description

3,5-Dibromo-4-Hydroxybenzoyl Chloride is a highly reactive aromatic acid chloride derivative, primarily used as a versatile building block in advanced organic synthesis. Its core value lies in its ability to introduce the 3,5-dibromo-4-hydroxybenzoyl moiety into target molecules, enabling the creation of compounds with specific functionalities. This intermediate is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring halogenated phenolic structures.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and plant growth regulators where the dibromophenol group imparts biological activity.
• Liquid Crystal Materials: Serves as a building block for mesogenic compounds used in display technologies.
• Polymer Chemistry: Monomer for producing specialty polymers, including high-performance polyesters and polyamides with enhanced flame retardancy.
• Dyestuff and Pigment Intermediate: Employed in the synthesis of halogenated dyes and organic pigments.
• Chemical Research & Development: A valuable reagent for academic and industrial research in medicinal chemistry and material science.

Quality Control

Our 3,5-Dibromo-4-Hydroxybenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets precise customer specifications and high-purity standards for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 and reactivity as an acid chloride, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from strong bases and sources of moisture.
