a13a21a32

a13a21a32 is an alphanumeric sequence that appears in several technical and scientific contexts as a designation, identifier, or code. Its structure consists of the lowercase letter “a” followed by three pairs of digits separated by the same letter, forming a pattern that is easily recognizable in databases and catalogues.

In computer science, a13a21a32 is sometimes used as a placeholder for a cryptographic hash or version string in software documentation. The format allows developers to illustrate example identifiers without revealing actual data, and it is frequently encountered in programming tutorials, test suites, and configuration files.

Within the field of chemistry, the sequence has been adopted as an internal reference for a series of polymer samples. Researchers have used a13a21a32 to label a specific batch of polyacrylamide where the numbers correspond to the molecular weight range and synthesis batch, facilitating traceability in experiments and publications.

Astronomical catalogues occasionally assign similar alphanumeric strings to minor celestial objects during preliminary observation phases. In such cases, a13a21a32 may denote a temporary designation for a newly detected asteroid before a formal name is approved by the International Astronomical Union.

Overall, a13a21a32 serves as a versatile placeholder across disciplines, providing a concise, unambiguous label that can be readily indexed, searched, and referenced without implying any proprietary information.
