Quality Control

Every batch of Acetyl Acetate: (1R,4Z,9S)-4,11,11-Trimethyl-8-Methylidene-Bicyclo[7.2.0]Undec-4-Ene is produced and tested under a strict quality management system. We employ advanced analytical techniques including GC, HPLC, and NMR to ensure identity, purity, and chiral integrity meet the exacting standards required for synthetic applications. Certificates of Analysis (COA) detailing all critical parameters are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to light and oxidation, prolonged exposure to air or light should be avoided to maintain product integrity.
