Quality Control

Every batch of Dansyl-Ala-Arg-Oh is produced under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our standard grade meets high-purity specifications suitable for research and development applications. Certificates of Analysis (COA) detailing HPLC purity, chiral purity, and other critical parameters are provided with each shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider storing under an inert atmosphere.
