A compound-style code on the extension that signals reference material, not retail.
Extension matters most when the second-level string is neutral. GL22 gives nothing away commercially — it looks like an internal designation — and .org tilts that neutrality toward scholarship: registries, consortia, protocol libraries, published methods. Readers arriving at an .org expect documentation and disclosure rather than a shopping cart, and that expectation is an asset in peptide research, where trust is built on method transparency.
The natural owner is a research foundation, university group, standards body or open-data initiative organizing literature around a single compound or compound series. A descriptive name would drown in synonyms; a four-character code becomes the citation itself, easy to reference in a paper, a slide or a footnote.
