Description

3-(3,5-Dibromo-2-Hydroxyphenyl)Pyrazole is a halogenated pyrazole derivative, a versatile and high-value organic intermediate prized for its unique molecular scaffold. This compound matters for its role as a critical building block in the synthesis of complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and inflammatory diseases.
• Agrochemical Synthesis: Serves as a core scaffold for developing new-generation herbicides, fungicides, and plant growth regulators with enhanced efficacy.
• Material Science Research: Used in the development of organic semiconductors, liquid crystals, and advanced polymers due to its rigid, brominated aromatic structure.
• Chemical Biology Probe: Employed in medicinal chemistry for structure-activity relationship (SAR) studies and as a fragment in fragment-based drug discovery (FBDD).
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving global clients.
