Indocyanine Green (ICG), identified by CAS number 172616-80-7 and often known by its designation IR-820, is a vital compound in modern medical diagnostics and research. As a highly effective infrared blood pool contrast agent and near-infrared (NIR) fluorescent dye, ICG plays a crucial role in visualizing biological processes that are otherwise difficult to observe.

The primary utility of ICG lies in its ability to act as a tracer. When administered intravenously, it binds to plasma proteins and circulates within the bloodstream, allowing medical professionals and researchers to monitor blood flow and tissue perfusion. This is particularly important in applications such as detecting diseased tissue in live animals, a key use in preclinical research and veterinary medicine. The dye's spectral properties, emitting fluorescence in the near-infrared spectrum, are advantageous as these wavelengths can penetrate deeper into tissues than visible light, reducing background interference and providing clearer imaging.

For those looking to buy Indocyanine Green, understanding its specifications is key. The compound is typically supplied as a green powder with high purity, often exceeding 97%, and a melting point above 300°C, indicative of its stability. This high purity is essential for accurate diagnostic results and reliable research outcomes. When sourcing this chemical, it is imperative to partner with a reputable manufacturer and supplier who can guarantee these quality standards.

The applications of ICG are diverse. In ophthalmology, ICG angiography allows for detailed visualization of the choroidal vasculature. Beyond that, it is used in various diagnostic procedures to assess hepatic function, cardiac output, and blood flow in different organs. Its role in preclinical research supports the development of new diagnostic techniques and therapeutic agents. For researchers and procurement managers, understanding the price of Indocyanine Green is also a consideration, especially for bulk purchases. Engaging with suppliers for quotes can often lead to cost savings without compromising on quality.

The reliability of a supplier is paramount when dealing with sensitive diagnostic agents. A trusted source will not only provide a high-quality product but also ensure proper packaging, safe transportation, and timely delivery. This is critical for research institutions and healthcare providers who depend on a steady supply chain for their ongoing operations. For example, a reliable manufacturer in China can offer competitive pricing for organizations looking to purchase this essential compound.

In conclusion, Indocyanine Green (IR-820) is a cornerstone diagnostic and research tool. Its capabilities as an infrared contrast agent and NIR dye make it indispensable in many medical and preclinical fields. When procuring ICG, prioritizing quality, purity, and a dependable supply chain from a trusted supplier will ensure the successful application and advancement of critical scientific and medical endeavors.
