Quality Control

Our production of this specialty intermediate adheres to strict quality management systems. Every batch is analyzed to ensure consistent chemical composition and performance characteristics critical for downstream dye synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and relevant physical parameters is provided with each shipment to guarantee traceability and compliance with your specifications.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent degradation from atmospheric moisture.
