Quality Control

Our 4-Propoxy-2-Butyn-1-Ol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography and spectroscopy, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to the presence of reactive functional groups, it is recommended to store under an inert atmosphere for long-term stability and to minimize oxidation risk.
