Some chemical suppliers seem to have autogenerated items, some/many are non-sense and I guess they just hope that you find something and they can make it? I found the example below a while ago but they have since removed it.
No, its not impossible. You can make it in the lab without too much difficulty if you have liquid nitrogen. Just not sold like this and you can't really contain it in a practical vessel as the pressure at room temperature would be too extreme, you store liquids or compressed gases.
Off topic, but I Googled "argon powder" and the AI overview thing hallucinated that the term means metal powders used for 3D printing, stored under argon to prevent oxidation. There are no actual results using the term in that sense, as far as I can tell.
Google search should not be returning an incorrect hallucination that sounds plausible ahead of the actual search results. It's so confidently wrong. Google is SO BAD NOW at searching for specific expressions.
