Quality Control

Our Fema 3604 is produced and tested to meet the stringent requirements of the flavor and fragrance industry. Quality is assured through rigorous analytical protocols including gas chromatography (GC) and sensory evaluation. A Certificate of Analysis (COA) detailing purity, identity, and organoleptic properties is provided with each batch to ensure compliance with FEMA, FCC, and relevant food safety standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and light-sensitive nature, store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Use under an inert atmosphere for prolonged storage to maintain optimal quality and prevent oxidation.
