Quality Control

Our 1,1'-Dibutyl-3,3,3',3'-Tetramethyl-Indadicarbocyanine Perchlorate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, UV-Vis-NIR spectroscopy for absorbance profile verification, and elemental analysis. Certificates of Analysis (COA) detailing batch-specific results are provided to ensure traceability and compliance with your research or production specifications.

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 material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under low-light conditions to maintain stability and performance.
