Quality Control

Our Ethyl 2-Bromo-5-Chlorooxazole-4-Carboxylate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, typically ≥97% (HPLC). Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We adhere to cGMP principles where applicable, supporting our commitment to supplying reliable intermediates for critical research and development pipelines.

Storage

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