Quality Control

Our Benzoic acid azo dye intermediate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for purity and spectrophotometric analysis for chromophore strength. Comprehensive Certificates of Analysis (COA) documenting identity, assay, and impurity profiles 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, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect performance.
