Description

HCFC 221 is a hydrochlorofluorocarbon compound with the CAS registry number 422-26-4, serving as a transitional refrigerant and chemical intermediate. This product is valued for its specific balance of properties, offering a lower ozone depletion potential (ODP) compared to earlier CFCs while maintaining useful solvency and volatility. It is primarily required by manufacturers in the refrigeration, air-conditioning, and specialty chemical synthesis sectors seeking compliant alternatives for specific applications.

Application

• As a transitional refrigerant and blowing agent in foam manufacturing.
• As a specialty solvent and cleaning agent for precision electronics and metal parts.
• As a chemical intermediate in the synthesis of fluorinated compounds.
• In fire suppression systems as a component of certain halon replacements.
• For laboratory research and development involving fluorocarbon chemistry.
• In the calibration of analytical instruments and environmental monitoring equipment.

Quality Control

Our HCFC 221 is produced and tested under a rigorous quality management system to ensure batch-to-batch consistency and compliance with relevant industry specifications. We provide comprehensive Certificates of Analysis (COA) for each shipment, detailing purity, impurity profiles, and physical properties. Our quality protocols are designed to meet the demands of industrial and research applications where material integrity is critical.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and reactive metals. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent loss and maintain purity. Recommended storage temperature is between 15°C and 25°C.
