Quality Control

Our 4-Methyl-4-Penten-2-Yn-1-Ol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP and ISO 9001 standards for quality assurance, ensuring reliability for your critical synthesis workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to the presence of unsaturated bonds, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize potential oxidation or polymerization.
