Quality Control

Our Thiolanediol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with major regulatory frameworks, and our quality systems are designed to meet the stringent requirements of the pharmaceutical and fine chemical industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents, heat, and ignition sources.
