Quality Control

Our Ethyl 5-(3-Bromophenyl)-5-Oxovalerate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes. We adhere to cGMP principles where applicable to support our clients' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 heat and incompatible materials.
