Quality Control

Our 1-Amino-3-Butene Hydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment.

Storage

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