Description

1-Bromo-1-Fluoroethane is a versatile halogenated alkane building block used in advanced organic synthesis. Its primary value lies in its ability to introduce both bromine and fluorine atoms into target molecules, enabling the creation of complex fluorinated compounds. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors who require precise fluorination and functionalization.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, pesticides, and fungicides where the fluorine atom improves efficacy and environmental profile.
• Organic Synthesis Reagent: Serves as an electrophile in alkylation reactions and as a precursor for generating fluorinated carbanions and other reactive intermediates.
• Fluoropolymer & Specialty Materials: Employed in the research and development of novel fluorinated polymers, liquid crystals, and electronic materials.
• Refrigerant & Propellant Research: Investigated as a potential component or precursor in next-generation, low-global-warming-potential refrigerants and propellant blends.

Quality Control

Our 1-Bromo-1-Fluoroethane is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research and production standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat sources and open flames. Recommended storage temperature is 2-8°C to minimize degradation and pressure buildup. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
