Quality Control

Our Azoic Coupling Component 107 is manufactured under a strict quality management system to ensure it meets the high-purity standards required for sensitive dye and pigment synthesis. Each batch undergoes comprehensive analytical testing, including assay and impurity profile determination. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
