Your request is too vague. When it comes to expiring chemicals, there are chemicals that have indefinite shelf life, as you noted, and some with shelf lives of days weeks or months. As the manager of the inventory, it is incumbent on you to determine the expiration standards for each reagent in your inventory.
That said, please inspect your inventory immediately for peroxidizables (ether, tetrahydrofuran, unstabilized anhydrous propanol, etc.), dry picric acid, and non-stabilized monomers. If you encounter any of those, back away. Consider enlisting the aid of an environmental service if your inventory is extensive.

Our research lab is currently updating the chemical inventory. Other than bottles/containers that are broken/cracked, I'd appreciate any advice on discerning which chemicals can be purged or disposed of. Many of the chemicals are dated over 20 years ago, but I know of at least a few that have an indefinite shelf life.
Any guidance in this area is quite welcome.
