CnX

CnX is an alphanumeric designation that appears across multiple domains, and it has no single, universally accepted definition. The meaning of CnX is determined by context, where n is typically an integer and X a placeholder for another variable element. In chemistry and materials science, CnX is often used in generic notation to denote a carbon chain or polymer segment consisting of n carbon atoms with a substituent or functional group represented by X. The specific identity of X and the range of n are defined by the reaction or material system under discussion.

In computing and technology, CnX can function as a product code, model name, or shorthand in documentation. It may label software releases, hardware configurations, or project initiatives, with the exact interpretation provided where the term is introduced.

In culture and media, CnX occasionally appears as an initialism for fictional organizations, projects, or brands. Because it is a compact, pronounceable form, it is well suited to speculative fiction and world-building.

Because CnX is not tied to a particular field, readers should consult domain-specific sources to determine its intended meaning in a given document. See also CNX for potentially different uses that are unrelated to CnX.
