Quality Control
Our But-2-En-2-Ol, (E)- is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high chemical and isomeric purity. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee batch-to-batch consistency and traceability for your R&D and production needs.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its properties, it is recommended to store this material under an inert atmosphere (e.g., nitrogen) to minimize oxidation and in a dry environment to prevent degradation. Keep away from strong acids and oxidizing agents.
