Quality Control

Our 1-(4-Dodecylphenyl)-2-Hydroxy-2-Methylpropan-1-One is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets high-performance industry standards for photoinitiators. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain efficacy. For long-term storage, consider an inert atmosphere (e.g., nitrogen).
