Quality Control

Our 1-Bromo-2,2-Dimethoxypropane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) are provided with every shipment, detailing specifications for identity, assay, and impurity profiles. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
