Short compound code in the extension research bodies and registries have always used.
The .org suffix still reads as institutional: societies, consortia, standards groups, open registries. Attach it to a four-character designation and you get something that sounds less like a storefront and more like a reference. GL28.org would be at home on a monograph page, a consortium charter, or a repository of published assay results, where credibility comes from restraint rather than marketing.
The natural owners are groups organized around a compound or a class of them — a multi-site research collaboration, a nonprofit publishing analytical standards, a scientific advisory body, or an educational archive for clinicians and investigators. A commercial-sounding name undercuts that work. This one signals documentation and stewardship from the first glance.
