Quality Control

Our 3-Bromo-3-penten-2-one is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and GC-MS for identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flames. It is compatible with strong acids and organic solvents but should be stored separately from incompatible materials.
