AICAR is a small-molecule nucleoside — acadesine, also known as AICA riboside — and one of the handful of non-peptide compounds in the catalog. It is supplied as a crystalline solid.
It is offered as a single reference lot, with independent per-lot analysis you can read before ordering and look up afterward by lot number.
A note specific to this one: the name 'AICAR' is used for more than one closely related species, so identity here is pinned to the registry record rather than the name alone — the item is the cell-permeable riboside. It is documented as dissolving in several common laboratory solvents, and it is stored frozen.
