Quality Control

Our [[2-(Hydroxyphenyl)-1-Methyl]Ethyl]Ammonium [R-(R*,R*)]-Tartrate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with stringent specifications for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) documenting identity, purity, and chiral excess are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 stability and handling properties.
