Description

4-Fluorobenzylurea is a versatile fluorinated organic building block of significant interest in advanced chemical synthesis. Its value lies in its role as a key intermediate for constructing more complex molecules, particularly in the pharmaceutical and agrochemical sectors. This compound is primarily needed by research institutions and industrial manufacturers developing active pharmaceutical ingredients (APIs), crop protection agents, and specialty materials.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, anti-cancer agents, and enzyme inhibitors.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and pesticides, where the fluorine atom enhances biological activity and metabolic stability.
• Material Science Research: Serves as a monomer or modifying agent in the creation of specialty polymers and advanced organic materials with tailored properties.
• Chemical Biology & Proteomics: Employed as a building block for activity-based probes and molecular tags used in studying biological pathways and protein functions.
• Liquid Crystal & OLED Materials: Acts as a synthetic intermediate for fluorine-containing compounds used in electronic displays and organic light-emitting diodes.

Quality Control

Our 4-Fluorobenzylurea is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific data 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 after opening to prevent degradation from atmospheric moisture.
