Quality Control

Our 2,6,6-Trimethylbicyclo[3.1.1]heptane-1-thiol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and chiral HPLC, to ensure identity, purity, and enantiomeric excess meet stringent specifications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated place at 2-8°C or as specified on the label. Due to its highly volatile and easily oxidized nature, prolonged exposure to air, heat, or light should be avoided.
