Description

New Indocyanine Green is a near-infrared fluorescent dye and diagnostic agent, distinct from the classical indocyanine green (ICG) with CAS 3599-32-4. This compound, identified by CAS number 172616-80-7, is valued for its enhanced photophysical properties and stability, making it a critical tool for advanced imaging and diagnostic applications. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and medical device sectors who require high-purity, specialized agents for optical imaging, fluorescence-guided surgery, and diagnostic assays.

Application

• Fluorescence-Guided Surgery (FGS): Used as a contrast agent to visualize tumors, blood flow, and lymphatic systems in real-time during oncological and vascular procedures.
• Near-Infrared (NIR) Imaging: Serves as a key component in preclinical and clinical research for deep-tissue imaging due to its optimal excitation and emission profiles.
• Diagnostic Agent Development: Employed in the formulation of diagnostic kits and reagents for detecting specific biomarkers or physiological functions.
• Ophthalmic Angiography: Applied in retinal and choroidal imaging to diagnose and monitor vascular disorders of the eye.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer for targeted cancer treatments.
• Bioconjugation & Probe Synthesis: Acts as a versatile fluorophore for conjugating to antibodies, peptides, or nanoparticles to create targeted imaging probes.
• Liver Function Diagnostics: Utilized in specialized tests to assess hepatic blood flow and liver cell function.

Quality Control

Our New Indocyanine Green is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, spectroscopy for identity confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for diagnostic and research applications. Certificates of Analysis (COA) documenting full specifications are available upon request.

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