Quality Control

Our production of 2-[[6-[[4-(Ethylphenylamino)-6-Fluoro-1,3,5-Triazin-2-Yl]Amino]-1-Hydroxy-3-Sulpho-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure compliance with industry specifications for purity, strength, and impurity profiles. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and related substances 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). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product quality.
