Quality Control

Every batch of 4-Bromo-Butyrimidic Acid Ethyl Ester is produced under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee reliable and reproducible performance in your synthetic processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
