Quality Control

Our 9-Hydroxybenzo[H]Quinoline-8-Carboxylic Acid is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production specifications. Custom purity grades and analytical packages are available upon request.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed and away from direct light sources to maintain stability and purity.
