Quality Control

Our 3,N4-Ethenocytosine is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards for fine chemicals and can provide material tailored to specific research-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
