Quality Control

Our production of this dye adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and tests for insolubles and heavy metals. A detailed Certificate of Analysis (COA) documenting all specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to prevent absorption of water.
