Your question supplies its own answer, though you may need to ensure the bottle's material will withstand the intended reagent.
The solution must by homogeneous.
This means that the material is of a standard specified by ACS, the American Chemical Society. Usually, it is purer than things marked simply "Reagent"
If the cover of a reagent bottle is placed on a table with the bottom down, it can pick up material from the table which would contaminate the contents of the reagent bottle after the cap is put back on the bottle.
The stopper of a chemical reagent container should be handled carefully for two reasons. Firstly, it may contain chemical residues which can be dangerous. Additionally, if the stopper is dirtied it may contaminate the reagent in the bottle when the stopper is put back on.
