The ampules are intended for one-time use only. For any remaining material, it is advised to transfer it to a bottle with a screw cap in a glove bag under inert atmosphere instead of trying to re-seal the glass ampule. It's important to note that this material is highly sensitive to air and water, so it cannot be guaranteed that the material will not degrade once the ampule has been opened and the contents transferred to a new bottle.

Application
Tetrakis(dimethylamido)titanium(IV) (TDMAT) is a precursor to titanium nitride (TiN) thin films by organometallic chemical vapor deposition (OMCVD)[1]and titanium dioxide thin films by atomic layer deposition (ALD).[2][3][4]TDMAT undergoes exothermal reaction with excess cyclopentadiene to yield tris(dimethylamido)(η5-cyclopentadienyl)titanium(IV).[5]

What sealing procedure was used for the ampule containing 469858-5G? There were issues when attempting to reseal the ampule using parafilm. Therefore, a resealing procedure is needed to ensure that the contents can be used over time without crystallizing.
