The 35-year-old tucked in a tidy finish after a swift Brighton break, bringing him up to 99 goals for the Seagulls.
He missed two chances to get a century, heading narrowly over on two occasions in the second half.
Murray said after the match that he was determined to get to the landmark.
"I'll be happy to see the 100th goal come and go," he told his club's official website.
"I had a couple of half-chances to get the 100th, maybe I should have done better with one, but it wasn't to be.
"It'll be a huge achievement to look back on, to get 100 goals for Brighton, but as soon as it's come and gone, the better, because it will be an extra goal in the tally.
"At my age you don't take playing in the Premier League for granted.
"So I'm taking a bit of extra time to appreciate where I am; enjoy playing in front of a packed home crowd. It's not going to last forever, so you have to make the most of it."
