Quality Control

Our α-n-Propyldecalin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
