Quality Control

Our 5-Octyn-3-Ol is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to verify identity, potency, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality attributes. For customers with specific regulatory needs, we can supply material with supporting documentation tailored to cGMP, ISO, or other relevant quality standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents and acids. For long-term storage, consider maintaining the product under an inert atmosphere (e.g., nitrogen or argon) to prevent potential oxidation.
