Quality Control

Every batch of 2-Octadecyl-15-Cyclopropylpentadecanoic Acid Methyl Ester is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including chromatography and spectroscopy, is performed to verify identity, purity, and consistency. A Certificate of Analysis (COA) documenting all critical specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, minimize headspace in opened containers and handle under inert gas when possible to maintain product integrity.
