Quality Control

Every batch of o-Cresol-3,4,5,6-D4,Od is produced and tested under strict quality management protocols to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm isotopic enrichment and chemical identity, ensuring compliance with the high standards required for analytical reference materials. A comprehensive Certificate of Analysis (COA) detailing batch-specific results for purity, isotopic enrichment, and solvent content is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which could affect purity and stability.
