14C9

14C9 is an alphanumeric designation used in several unrelated fields. There is no single universally recognized definition for 14C9; its meaning depends heavily on context.

In radiocarbon research, "14C" denotes the isotope carbon-14. When paired with a trailing digit such as "9," the string often functions as a lab sample identifier or run number (for example, a particular aliquot or measurement batch). In this sense, 14C9 does not indicate a chemical species or compound but a data label within a project or dataset.

In organic synthesis or radiolabeling, "14C" can indicate isotopic labeling with carbon-14. A descriptor like "14C9" might refer to labeling at a specific carbon atom in a molecule, with the digit indicating the position or labeling site, but such usage requires explicit definition in experimental methods.

In manufacturing or inventory systems, 14C9 can be a catalog, part, or lot code. Codes of this pattern are common in electronics, automotive parts, and laboratory supplies and do not imply scientific properties.

Because of its cross-domain use, the term 14C9 usually appears alongside clarifying information such as "sample 14C9," "14C labeling at position 9," or "part 14C9." See also carbon-14, isotopic labeling, and cataloging systems.
