Description

Benzaldehyde, 4,5-Difluoro-2-Hydroxy- (9Ci) is a specialized fluorinated benzaldehyde derivative, serving as a high-value synthetic intermediate in advanced organic chemistry. Its core value lies in the strategic placement of fluorine atoms and a phenolic hydroxyl group, which are critical for modulating the electronic and steric properties of target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors, where it is used to develop novel active ingredients with enhanced potency and metabolic stability.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of fluorinated drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the research and production of next-generation herbicides and pesticides, where fluorine incorporation improves biological activity and environmental persistence.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorinated aromatic cores in electronic display and lighting materials, contributing to improved performance and stability.
• Advanced Polymer Chemistry: Employed as a monomer or modifier to introduce fluorine and phenolic functionality into high-performance polymers and resins.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D in medicinal chemistry and material science for structure-activity relationship (SAR) studies.
• Fluorinated Fine Chemicals: Intermediate for the manufacture of other complex, multi-fluorinated fine chemicals and specialty reagents.

Quality Control

Every batch of Benzaldehyde, 4,5-Difluoro-2-Hydroxy- (9Ci) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC for purity and identity confirmation, is performed. Certificates of Analysis (COA) detailing all specifications and test results are provided with each shipment and are available upon request.

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 tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
