Quality Control

Our 1-[5-(tert-Butyl)-2-Hydroxyphenyl]Ethan-1-One is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques like HPLC, GC, and NMR to confirm identity and assay. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize contact with air.
