Quality Control

Our 2-(4-Chloro-3-Hydroxy-1-Butynyl)-5-(1,3-Pentadiynyl)Thiophene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each 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 (typically 15-25°C). Keep away from heat, sparks, and open flames. Due to the functional groups present, this material should be considered moisture-sensitive (hygroscopic) and handled under an inert atmosphere for long-term storage to prevent degradation.
