1CR1

1CR1 is a four-character alphanumeric designation used as an identifier across various information systems. Unlike descriptive names, such codes convey information only within a particular catalog, database, or product line, and their meaning depends on the issuing authority.

In scientific data repositories, four-character codes are common. If 1CR1 is encountered in the Protein Data Bank or a related structural biology resource, it would designate a specific data entry corresponding to a single molecular structure. The entry would typically include metadata such as the deposited authors, experimental method, resolution, organism of origin, and the coordinates of the atoms comprising the structure. Access to the full details would require querying the exact database with the code 1CR1.

Beyond science, 1CR1 appears in commerce and manufacturing as a model or part number. It may identify a particular product variant, batch, or component in catalogs, inventories, or sales systems. In such contexts, the prefix or suffix around the code, as well as the vendor, is necessary to determine its semantics.

Because 1CR1 is a generic code rather than a descriptive name, its precise referent is context-dependent. When encountering 1CR1, readers should identify the owning database or catalog and locate accompanying metadata to interpret the code correctly.
