Quality Control

Our Pyrazolo[1,5-A]Pyrimidine-5-Acetic Acid, 7-Hydroxy-2-(4-Methoxyphenyl)-, Ethyl Ester (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We support development and commercial projects with material suitable for research use and can supply grades aligned with cGMP guidelines for advanced pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). This material may be light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under inert atmosphere when not in use to prevent degradation and moisture absorption.
