Quality Control

Every batch of 3,4-Dehydro Cilostazol-D11 is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure the highest standards of chemical purity and isotopic enrichment. Our quality protocols are designed to meet the stringent requirements of analytical reference standard applications. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), isotopic purity (by MS), and identity confirmation is provided with each shipment.

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 compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
