Hydrofluoric. Burns through silicates and supertoxic, causing tetany and cardiac arrest through fluoride poisoning.

My very first job involved that shit, calcium gluconate gel as a first aid response seemed like a good idea at the time, you wouldn't get me anywhere near it all now!

Yeah, rub the gel on after its penetrated the subcut fat and is already producing stalactites in your arteries :)

Yep. I was a research chemist for 20yrs & HF was one of the few things I refused to use - TBAF was perfectly fine for when I needed a fluoride source.

I'm guessing NaF was no use?

I was an organic chemist, so mostly working in organic solutions due to low substrate water solubility (esp for fatty t-butyldimethylsilyl deprotections). I used commercially available TBAF in THF. Or if my stuff was acid stable, just stir it with tosic acid or CSA.

I once read a protocol for using acyl chlorides in aqeuous solution. Took it to an organics prof. He said yeah don't always believe the methodology even if you insist on believing the results :D

Lol. Yeah! Often it's crossover stuff from one discipline to another (phys chem to org chem or vice versa). I did a project on cadmium mercury telluride IR-detection materials & we had to clean the surface with bromine/methanol! My organic prof told me Br2 oxidizes methanol. Lol.

It'd be clean. No ways about it.
