Description

1-Bromo-1-Fluoroethylene is a versatile halogenated olefin building block of significant industrial importance. Its unique structure, featuring both bromine and fluorine atoms on the same carbon, makes it a valuable precursor for synthesizing advanced fluorinated polymers and fine chemicals. This compound is essential for R&D and production in the pharmaceutical, agrochemical, and specialty materials sectors, where it is used to introduce fluorinated vinyl groups. We supply high-purity 1-Bromo-1-Fluoroethylene CAS NO 420-25-7 to meet the stringent demands of global industrial and research applications.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing novel fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in the production of advanced herbicides, pesticides, and fungicides that benefit from the stability and lipophilicity imparted by fluorine.
• Fluoropolymer Monomer: Acts as a co-monomer or modifier in the synthesis of specialty fluoropolymers and elastomers with enhanced chemical resistance and thermal stability.
• Organic Synthesis Reagent: Employed in cross-coupling reactions, cycloadditions, and as a fluoroalkylating agent in academic and industrial R&D laboratories.
• Liquid Crystal & OLED Materials: A precursor for creating fluorinated components in electronic display materials and organic light-emitting diodes (OLEDs).
• Refrigerant & Propellant Research: Investigated as a potential component or intermediate in next-generation, low-global-warming-potential (GWP) fluorocarbon blends.

Quality Control

Our 1-Bromo-1-Fluoroethylene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practice (GMP) principles where applicable. Each lot is thoroughly analyzed using advanced techniques including GC, GC-MS, and NMR to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) to maximize stability and shelf-life. Keep away from strong acids, bases, and oxidizing agents.
