Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for fragrance and fine chemical applications. Each batch is analyzed using GC, GC-MS, and NMR to confirm identity, purity, and olfactory profile consistency. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents.
