Quality Control

Our Yellow Pyoctanine is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which typically include identity confirmation, assay, and impurity profile analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your research or production requirements.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to prevent degradation.
