Quality Control

Our 1,3-Butylenesulfate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure it meets the required specifications for your application. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
