Yes, "last minute" is an adjective used to describe when you do something at the last possible moment or opportunity for something. For example, you have an exam at 10 AM and you only started studying at 8 AM. That would be considered to be very last minute. To use it as a noun, you can precede it with "at the." Ex: I need to fix my habit of doing everything at the last minute. Ex: I did some last minute errands before going on vacation.
