Small molecules are chemically synthesized, low molecular weight compounds. In contrast, biologics are high molecular weight proteins, monoclonal antibodies (mAbs), vaccines, or gene therapies produced in living systems. Their inherent complexity and sensitivity to environmental factors necessitate different approaches in stability testing.
