Quality Control

Our fragrance-grade 2-(3,3-Dimethylbicyclo[2.2.1]Hept-2-Ylidene)Ethyl Isobutyrate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and organoleptic evaluation, to ensure consistent purity, olfactory profile, and compliance with IFRA guidelines for safe use. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity limits is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening and minimize headspace in containers to preserve stability and fragrance integrity. Keep away from heat, sparks, and open flame.
