Quality Control

Our n-Pentane is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography, to ensure it meets precise purity and compositional specifications. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical properties are available for review and provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is below 30°C. Keep away from strong oxidizing agents.
