Quality Control

Our Ethyl Stilbene-4-Carboxylate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment, ensuring full traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
