Quality Control

Our 4-tert-Butyl-3-Methylanisole is produced under a stringent quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for fragrance and technical applications. Key parameters such as identity, assay, and olfactory profile are verified. A Certificate of Analysis (COA) documenting purity, physical properties, and chromatographic data is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Keep away from heat, sparks, and open flame.
