Quality Control

Our Difluoromethane is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and reliability. We adhere to relevant industry standards and can provide material tailored to specific purity requirements, including high-purity grades for pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for every batch upon request, ensuring full traceability and compliance with your procurement specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature under standard conditions, it must be stored in approved pressure-rated cylinders or containers in a cool, well-ventilated area away from direct sunlight, heat sources, and incompatible materials such as strong alkalis. Storage temperature should be maintained below 30°C (86°F).
