Description
NIR-820 Heptamethine cyanine NEt3H+ is a polymethine dye with empirical formula C₅₂H₆₆ClN₃O₆S₂ and CAS number 289893-03-4. This near-infrared cyanine shows an absorption maximum of 820 nm in methanol and a molar mass of 928,69 g/mol. The heptamethine structure with triethylammonium counterion offers a characterised framework for work on optical properties deep in the near-infrared region. Available from manufacturer Carl ROTH under EG number 812-366-6, the product belongs to the polymethine dye class applied where strong absorption around 820 nm is needed for method development, comparative screening, or formulation trials. facilitates precise handling in analytical and synthetic laboratories that require controlled quantities of specialised dye for imaging-related and optical materials applications.
