  Entanglement is a purely quantum mechanical phenomenon and thus it has no
classical analog. On the other hand, coherence is a well-known phenomenon in
classical optics and in quantum mechanics. Recent research shows that quantum
coherence may act as a useful resource in quantum information theory. We will
employ here quantum coherence to detect and classify the entanglement property
of three-qubit states. Moreover, we have shown that if any three-qubit state
violates another necessary condition for the detection of a general biseparable
state then the given three-qubit state cannot be a biseparable state. Since
there are only three categories of states for the three-qubit system so if we
detect that the state under probe is neither a separable nor a biseparable
state then we can definitely conclude that the given three-qubit state is a
genuine entangled state. We have illustrated our results with a few examples.
