Quality Control

Our production of S-(tert-Butyl) 12-Hydroxyoctadecanethioate adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
