LCMS-grade Ammonium formate shortage?

[bisnettrj2]

Has anyone noticed any difficulties in acquiring LCMS-grade ammonium formate? My suppliers have been backordered for the past few weeks.

I usually order from Fisher Scientific and they have some in stock from Honeywell. They also have some AmForm solutions, 10 mM in water or methanol in stock from ThermoFisher.

However, I don't order it often.

Not ammonium formate (we usually use ammonium acetate, which we have reasonable stock of) but LC-MS grade ammonia solution (from Merck). We're on backorder for the next couple of months and down to our last bottle. Not sure where the supply chain hiccup is happening...
