Quality Control

Our 4,4-Diphenylsemicarbazide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, IR, and loss on drying, to verify its identity, potency, and conformance to established specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
