Quality Control

Our 10-Thiastearic Acid is produced under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including identity confirmation by spectroscopic methods (IR, NMR) and purity assessment by chromatographic techniques (HPLC, GC). We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your research and production specifications.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture uptake and oxidation.
