Quality Control

Our N,N'-Dioctadecyloxacarbocyanine p-Toluenesulfonate is manufactured under strict quality systems to ensure batch-to-batch consistency and a purity of 99% (typical). Each lot undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes to support your research and compliance needs.

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 sealed in a desiccated environment and handled under low-light conditions to maintain stability and performance.
