Quality Control

Our production of 4-(Bromomethyl)-2,6-Ditert-Butyl-Phenol adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal quality and prevent degradation. Keep away from strong oxidizing agents.
