Quality Control

Our 2-Methyl-3-Pentyn-2-Ol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration of vapors. Recommended storage temperature is 2-8°C for long-term stability.
