Quality Control

Our α-Guaiene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. We employ advanced analytical techniques including GC, GC-MS, and chiral HPLC for precise identification and quantification. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess (where applicable), and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and potential changes in concentration. Keep away from heat, sparks, and open flame.
