Quality Control

Our 4-Aminobut-2-Yn-1-Ol Hydrochloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including HPLC for assay and impurity profiling, to meet the stringent requirements of our global clientele in advanced synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties. Keep away from incompatible materials.
