Quality Control

Our Pyridine-2-D1 is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high isotopic purity. Each lot undergoes comprehensive analysis, including assay by NMR or GC-MS, determination of isotopic enrichment (D-atom %), and verification of chemical and optical purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at a controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Keep away from heat, sparks, and open flame.
