Description

Benzene, 1-Fluoro-3-Isocyanato-5-Methyl- (9Ci) CAS NO 200509-15-5 is a specialized aromatic isocyanate derivative, distinguished by the presence of both a reactive isocyanate group and a fluorine substituent on the benzene ring. This unique molecular structure makes it a high-value building block for synthesizing advanced polymers and fine chemicals with tailored properties. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for creating novel compounds with enhanced stability and performance.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic motifs for metabolic stability.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the isocyanate group enables the formation of urea or carbamate linkages.
• Polymer Modification: Acts as a monomer or cross-linking agent in the production of specialty polyurethanes, polyureas, and coatings, imparting chemical resistance and durability.
• Liquid Crystal & OLED Materials: Employed in the research and manufacturing of advanced electronic display materials due to its ability to introduce fluorine atoms into conjugated systems.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D focused on fluorination chemistry and isocyanate-based reactions.
• Adhesive & Sealant Formulations: Contributes to high-performance formulations where moisture-curing properties and bond strength are critical.

Quality Control

Our production of Benzene, 1-Fluoro-3-Isocyanato-5-Methyl- (9Ci) adheres to stringent quality protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and FT-IR & NMR for structural confirmation, to ensure it meets exacting customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
