And you are the seller?

Is this a reputable brand of NaH being resold?

Or is someone making NaH in his basement?

What about QA/QC? Assay, elemental analysis?

If a repack from bulk id it done under appropriate anhydrous, inert atmosphere, e.g. in a glove bos?

Lastly one hoprs it is not the Chinese shit.

Inquiring minds want to know.

I honestly have no clue. But I do a bi-daily (it seems) search for reagents on ebay. Reducing agents (hydrides) seem hard to come by regularly.
I just assumed somebody might be interested.

If you consider it flooding the boards I won't do it.

dont worry about sauron he is just like that.

he sits in his dark castle on top of his dark hill planing dark things with 50L dark mantles hehe.

truly hydride is the least of his worries hes just like that.

never seen sodium hydride on ebay hazmat would probably kill me though and customs over here
are real tough but still never seen sodium hydride on ebay.

anyway sauron is into slave orc labour he has saruman making them up for him in his lab.
he has heaps worse than chinese "cough cough racist" crap he has orc shit.
:D

It's a shame from what I've gathered. The selective reduction of ketones to secondary alcohols leaves for limited choice of reagents.

Most reducers just aren't selective or not reducing enough.

The ones that work are hard to get a hold of.

NaH is not normally used as a reducing agent, but as a strong base.

It will only reduce ketones which have no alpha hydrogens.

See for example Fieser's Reagents for Organic Synthesis.

Hook up 100 Ephoton clones in series to an EEg and all you get is baseline noise.
