Quality Control

Every batch of Variolink CAS NO 179240-22-3 is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high purity and batch-to-batch consistency suitable for research and cGMP manufacturing. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and degradation. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture uptake. Keep away from strong acids, bases, and oxidizing agents.
