Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, GC, NMR, and mass spectrometry to verify identity, purity, and consistency for every batch. Certificates of Analysis (COA) are available upon request, providing full transparency on specifications and test results to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is between 2°C and 8°C for long-term stability, or at controlled room temperature for short-term use. Keep away from heat, sparks, and open flame. Handle and store under an inert atmosphere if specified for the specific grade to prevent decomposition.
