Description

Hydrochlorofluorocarbon-221 (HCFC-221) is a hydrochlorofluorocarbon compound primarily used as a transitional refrigerant and blowing agent. This product matters for industries seeking alternatives with lower ozone depletion potential than traditional CFCs, while maintaining effective thermodynamic properties. It is needed by manufacturers in the refrigeration, air conditioning, and foam insulation sectors, as well as for specialized applications in chemical synthesis and aerosol propellants. We supply high-purity HCFC-221 to meet diverse industrial requirements.

Application

• As a transitional refrigerant in commercial and industrial cooling systems.
• As a blowing agent for the production of polyurethane and polyisocyanurate foam insulation.
• As a solvent and cleaning agent in precision electronics and metal degreasing applications.
• As a propellant in specialized aerosol formulations.
• As an intermediate in chemical synthesis for fluorinated compounds.
• In fire suppression systems as a component of certain blends.
• For laboratory research and analytical standard preparation.

Quality Control

Our HCFC-221 is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including gas chromatography (GC), to verify purity and the absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. Our quality commitment aligns with industrial standards, and we can support compliance documentation for global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
