Quality Control

Every batch of 5-[(1R,4Aα)-Decahydro-2α-Hydroxy-2,5,5,8Aβ-Tetramethylnaphthalen-1β-Yl]-3-Methyl-2-Pentenal is manufactured and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
