Description

Pentafluoroethane CAS NO 354-33-6 is a high-purity, non-flammable fluorocarbon compound widely recognized as a key refrigerant and propellant. Its primary commercial value lies in its excellent thermodynamic properties and zero ozone depletion potential (ODP), making it a critical component in modern, environmentally compliant systems. This product is essential for manufacturers and service providers in the HVAC&R, pharmaceutical, and specialty chemical industries seeking reliable, high-performance alternatives to phased-out substances.

Application

• Refrigerant (R-125): A primary component in HFC refrigerant blends (e.g., R-404A, R-410A, R-507) used in commercial refrigeration, air conditioning, and heat pump systems.
• Fire Suppression Agent: Utilized as a clean extinguishant in specialized fire suppression systems for protecting sensitive electronic and archival equipment.
• Propellant: Serves as a non-flammable, low-toxicity propellant in metered-dose inhalers (MDIs) for pharmaceutical applications and in technical aerosol products.
• Chemical Intermediate: Used in the synthesis of more complex fluorinated organic compounds and polymers within advanced chemical manufacturing.
• Dielectric Gas: Employed in high-voltage electrical equipment and switchgear due to its excellent insulating and arc-quenching properties.
• Solvent & Carrier: Acts as a solvent in precision cleaning applications for electronics and as a carrier fluid in supercritical fluid extraction (SFE).

Quality Control

Our Pentafluoroethane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Every lot is analyzed against rigorous internal specifications, which typically include purity assay by GC, verification of non-flammability, and quantification of key impurities such as moisture and non-condensable gases. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with industry and regulatory standards, including those relevant to the AIM and F-Gas regulations.

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 and gaseous nature under ambient conditions, cylinders must be secured upright and handled in accordance with pressure gas regulations. Keep container valves tightly closed when not in use.
