GS-441524

1 Identity

Small molecule — an adenosine nucleoside analog. Not A peptide. Its presence in a peptide catalog is itself a finding. and sold into the veterinary feline infectious peritonitis gray market under several brand names.

Sequence

Not applicable. This article has no sequence and the concept does not apply. A small molecule with no sequence is nonetheless sold routinely inside peptide catalogs, which is a category error the market makes as a matter of course and this catalog does not repeat.

Molecular formula

C12H13N5O4

Average mass

291.26 Da.

Monoisotopic mass

291.09675 Da; [M+H]+ 292.10403.

Salt / variant note

Remdesivir itself, C27H35N6O8P, 602.6 Da — the phosphoramidate prodrug of this molecule, and a different article with a different regulatory status. GS-621763, the oral prodrug. Various nucleoside analogs at nearby masses. Material sold under the name GS-441524 in the feline infectious peritonitis channel has been repeatedly reported as under-strength or as a different compound entirely. One seller lists it as a 30 mg powder in a 10 mL vial, which is a peptide-trade presentation applied to a small molecule.

Identity and structure are settled and public. The evidence base for the veterinary use that drives demand is real but is not this company's to cite, and is not reproduced here.
