DEFINITION

Classification: 424/1.65

In an organic compound:

(under subclass 1.11) Subject matter in which the radionuclide or intended radionuclide comprises an organic compound.

(1) Note. An organic compound is defined by the following statement (which originated from the definition set forth in Class 260, Chemistry of Carbon Compounds, as qualified by

Note (34)): Compounds containing carbon which are further characterized by the presence in a molecule thereof of two carbon atoms bonded together, or one atom of carbon bonded to at least one atom of hydrogen or halogen, or one atom of carbon bonded to at least one atom of nitrogen by a single or double bond; including dicyanamide, dicyandiamide and salts thereof, which compounds, per se, are classified in Class 260; and excluding hydrocyanic acid, cyanogen, isocyanic acid, cyanamide, cyanogen halides, isothiocyanic acid, fulminic acid and metal carbides, all of which compounds, per se, will be classified in Class 423.

(2) Note. This subclass is the proper residual location for those class-appropriate compositions and uses having organic compounds not appropriate above or for a hereinunder indented subclass and having a radionuclide or an element intended to be converted to a radionuclide attached (bonded, chelated, complexed) thereto which is a metal. The analogous class-appropriate compositions and uses having organic compounds having attached thereto a nonmetal are proper for subclasses 1.81+, below.

(3) Note. A metal is any element other than a nonmetal. The nonmetals are: Hydrogen, Boron, Carbon, Silicon, Nitrogen, Phosphorus, Oxygen, Sulfur, Selenium, Tellurium, Fluorine, Chlorine, Bromine, Iodine, Astatine, Helium, Neon, Argon, Krypton, Xenon, and Radon; (H, B, C, Si, N, P, O, S, Se, Te, F, Cl, Br, I, As, He, Ne, Ar, Kr, Xe, and Rn.)
