Quality Control

Our production of Benzo[B]Thiophene-2-Carboxylic Acid, 3,6-Dichloro-, [(3,4-Dihydroxyphenyl)Methylene]Hydrazide (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized (store under inert atmosphere), prolonged exposure to air, light, or elevated temperatures should be avoided. Keep away from incompatible materials.
