Quality Control

Every batch of 3-(2,4-Dichlorophenyl)-1-Oxo-3,4-Dihydro-1H-Isochromene-4-Carboxylic Acid is manufactured under a strict quality management system and undergoes comprehensive analytical testing. Our products are guaranteed to meet high-purity standards suitable for research and development applications. A detailed Certificate of Analysis (COA) providing batch-specific data for identity, purity, and impurities is supplied with each shipment to ensure traceability and compliance with your internal quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
