Quality Control

Our production of C.I. Basic Red 46:1 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including color strength, shade, solubility, and impurity profile. Certificates of Analysis (COA) documenting these results are provided with every shipment. We maintain traceability and compliance with relevant global chemical inventory regulations to support our customers' supply chain integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials.
