No - remember sanitize is not the same thing as sterilize. When you sanitize something, you're only killing off most of the nasties, making sure that the good things in your beer have the best chance to out compete the bad things. If you sanitize something, seal it up, and then put it away, you're risking that any tiny populations of nasties (bacteria, wild yeast, whatever) may get the chance to build back up a sizeable colony before you unseal that bottle (or whatever) and use it.
Sanitize as close to the time you plan to use as possible!
