Quality Control

Our 2-(4-Acetoxy-3-Chloro-1-Butynyl)-5-(1,3-Pentadiynyl)Thiophene is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
