Quality Control

Our Hemiphroside A is produced under strict quality management protocols. Each batch is characterized using advanced spectroscopic and chromatographic techniques (NMR, HPLC, MS) to confirm identity and purity, ensuring it meets the stringent requirements for use as an analytical reference standard. A comprehensive Certificate of Analysis (COA) detailing purity, chromatographic profile, and storage recommendations is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
