Compound synonyms and aliases

The multiple names — codes, trade names, sequence names — under which one compound circulates, and the reason registry identifiers rather than names settle identity.

Most research compounds accumulate names: a development code from the originating programme, a chemical or sequence-derived name, trade names, and marketplace abbreviations. All of them are aliases for one underlying structure, and none of them is authoritative. The same compound can appear under three names on three vendor sites, and two different compounds can share a colloquial name.

Name drift has practical consequences for anyone searching the literature or comparing products. Published studies typically use the development code current at the time of the work, while marketplaces favour shorter aliases, so a literature search under the selling name can miss most of the evidence. The research pages on this site list verified synonyms for each compound and redirect alias URLs to the canonical page for the same reason.

Where names blur, identifiers settle the question: a CAS number, UNII or InChIKey refers to one substance definition regardless of what the label calls it. The practical rule is that names are for finding a compound and identifiers are for confirming it — and a product identified only by an alias, with no checkable identifier, has not actually been identified.
