Quality Control

Our Acid Yellow 114 is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including strength, shade, and solubility testing, to meet precise customer specifications. Certificates of Analysis (COA) documenting purity, dye content, and key physical-chemical parameters are available upon request to support your quality assurance processes.

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 to prevent absorption of atmospheric moisture, which can affect product performance.
