Quality Control

Our C19 Ceramide (D18:1/19:0) is produced under stringent conditions to ensure high purity and batch-to-batch consistency. Quality is verified through a comprehensive suite of analytical techniques including HPLC, MS, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each batch to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the product to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
