Applications by polymer
The TDS lists use as a solute in low-voltage aluminum electrolytic capacitor electrolyte. It also lists organic synthesis and liquid chromatography–mass spectrometry (LC–MS) mobile-phase use. Confirm the offered grade against the application.
Packaging & storage
Storage and transport
Keep tightly sealed in a cool, dry, ventilated warehouse. It is strongly hygroscopic and can deliquesce when exposed to air. Protect the bags against moisture and tears during transit.

Ammonium Formate FAQ
Why should the bag remain sealed?
The TDS describes the material as strongly hygroscopic. Exposure to moist air can cause it to deliquesce.
How is ammonium formate packed?
The standard package is a 25 kg bag.
What does the grade report for chloride?
The release standard lists chloride at ≤1 ppm. Confirm the lot against the applicable COA.
Can I get a batch COA?
A COA accompanies every batch. Ask for the applicable grade documents when you enquire.
