Quality Control

Our Methyl 1,4-Dihydroxy-7-Phenoxyisoquinoline-3-Carboxylate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC for assay and purity determination, and is accompanied by a detailed Certificate of Analysis (COA). We are committed to meeting the stringent requirements of research and development applications, with specifications tailored to client needs.

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 each use to prevent degradation from atmospheric moisture.
