C26

C26 is a designation used in several different fields, where it does not refer to a single item but to a category or identifier that depends on the context.

In chemistry, C26 commonly denotes a molecule or fragment containing 26 carbon atoms. The exact formula depends on the degree of saturation and on any functional groups present. For example, a fully saturated acyclic hydrocarbon with 26 carbons would have the approximate formula C26H54. Beyond that general use, C26 can also appear as a shorthand for carbon-chain length in various chemical catalogs or discussions.

In aviation and military contexts, C‑26 or C26 has been used as a designation for certain transport, utility, or support aircraft within different countries’ services. The precise aircraft model, operator, and service history vary by nation and era, reflecting the common practice of assigning short alphanumeric codes to equipment rather than prescribing a single universal meaning.

In other domains, C26 may appear as a route number, corridor code, product model, or catalog identifier within a particular organization or system. Such usage is highly specific to a given infrastructure or institution, and it may not be recognizable outside that exact context.

Because C26 is a generic, multi-domain designation, its exact meaning is highly context-dependent. When encountering C26, identifying the field of reference is essential to determine what the code stands for. If you have a specific domain in mind, providing that context can yield a precise definition.
