Quality Control

Our Pyrimidine, 5-(1-Chloroethyl)-2-(Methylthio)- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters 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 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.
