Yeah, unistrut, unistrut pipe clamp, and whatever you fancy to attach the unistrut to the concrete would be what I would expect to use.
I don't know that a pipe stand needs to be "listed". It seems like it was just the last edition of NFPA 13 where we finally got some kind of prescriptive advice on how to build pipe stands, other than the nefarious "where pipe stands are utilized, they shall be approved". Most jurisdictions I work in wouldn't question that method or expect an approved, engineered detail or anything, but I'm out in the Wild West, I guess.
