It is, but it will have common-mode voltage induced variation
in on-resistance that may bother the linearity. Smart choice
of how you use it can help that. Like attaching it at a virtual
ground point where signal is always roughly zero. Shunt vs
series, etc.
There are also packaging options out there that are smaller
than a TO-92 package, surface mount. Probably single
channel analog switches too. Presuming you like the voltage
range of the itty bitty ones which may be likelier to come in
low voltage.
