Quality Control

Our Hirsutidin Chloride is produced and handled under strict quality management protocols. Each batch is analyzed to ensure high purity and consistency, meeting the stringent requirements for analytical reference standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation (HPLC, MS), and related substance profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. This compound is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air, light, or moisture should be avoided to maintain stability and purity.
