Quality Control

Our Cyclohexanol,5-(1,1-Dimethylethyl)-2-Methylene-cis- is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high chemical purity and consistent isomeric composition. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Ensure containers are kept upright and properly sealed when not in use to minimize evaporation and potential contamination.
