Quality Control

Our Sulfonium 080W is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure consistency and performance. Certificates of Analysis (COA) documenting all critical specifications are provided with every shipment to guarantee compliance with your formulation requirements.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept sealed until ready for use in controlled lighting conditions.
