Quality Control

Our Cyclopropane, 1-(Bromomethyl)-2-Methyl- is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, and open flame. The container must be kept tightly closed in a dry and well-ventilated place. Containers that have been opened must be carefully resealed and kept upright to prevent leakage.
