Quality Control

Our 1-(Ethylsulfonyl)Piperazine Hydrochloride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and tests for residual solvents and moisture content, to ensure it meets the stringent requirements for pharmaceutical intermediate applications. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
