To account for such things as the photo-electric effect, the stability of atoms, the Periodic Table, atomic and molecular spectra, chemical bonding, the operation of the transistor (and thus of integrated circuits), just to name the few that immediately spring to mind.
QM is one of the two great pillars that support physical chemistry, the other being Statistical Mechanics (which itself relies on the principles of QM).

Yes, if you can imagine one without atoms and molecules.
Or you could make up any old stuff you like, really. But it would not be real, obviously, because observation of the real world tells us that it obeys QM.
