Abstract: A rotational scaled quaternion algebra is a ten-parameter four-dimensional real algebra whose automorphism group contains SO(2). We determine which of these algebras are division algebras and which are normed algebras. For the division algebras we determine all automorphisms and derivations and solve the isomorphism problem.
