Quality Control

Our fragrance and flavor ingredients are produced under strict quality management systems to ensure consistent organoleptic properties and chemical purity. Every batch is analyzed using GC, GC-MS, and IR spectroscopy to verify identity, strength, and the absence of undesirable impurities. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation, and olfactory profile is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep away from heat, sparks, and open flame.
