Quality Control

Our 5-Cyclopentyl-5-Ethylbarbituric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically ≥98% by HPLC), identity confirmation (by IR, NMR), and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
