What is the typical initial mass requirement for a single star to undergo a core-collapse supernova?

Answer

Greater than eight times the Sun's mass ($>8 M_{\odot}$)

Stars that initiate a core-collapse supernova must start with a substantial initial mass, generally cited as being more than eight times the mass of the Sun. This high mass is necessary to achieve the required core conditions.
