Quality Control

Our trans-11-Octadecenoic Acid Methyl Ester is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or manufacturing specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from strong acids, oxidizing agents, and heat sources. This material is easily oxidized and should be handled under appropriate conditions to maintain stability.
