Quality Control

Our 1-Ethynyl-4-Pentylbenzene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to verify identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen or argon) to prevent potential oxidation or polymerization.
