I'm getting ready to build a "Florida Room" on the back of our house.
I'm clearing out some bushes and plants to make way for the addition.
I found a 1.5" sch.40 PVC pipe running straight away from the house,
next to the driveway pad, in between the pad and where all the
vegetation was planted.

On the far end out near the vegetation, was a PVC threaded end cap with
a pipe-thread adapter and a pneumatic male coupler tool connector. The
nipple hole of the coupler had been sealed with what I think is pipe
solder. I drilled it out and it had the same consistency.

I sent a plumbing snake up the pipe towards the house and it hits right
near the foundation, but not any further in.

Any ideas what this was used for?

Moonshine bootlegging? ;~)
