Abstract: An algebra $ A$ over a field $ F$ will be called scalar dependent in case for every $ x,y,z$ in $ A$ there exists a function $ g(x,y,z)$ in $ F$ such that $ (xy)z = g(x,y,z)x(yz)$. The main result of this paper is that any scalar dependent algebra which contains a nonzero idempotent must always be associative. Since there are known to exist scalar dependent algebras which are not associative, the hypothesis regarding the existence of an idempotent is actually necessary.
