solubility
I recently received a sample of n-acetylcysteine amide to use as a standard for analysis. It came with specs that said it's solubility is "water to
100 mM".
The mw for it is 162.21. I am thinking they mean that up to 16.22 gms of the substance is soluble in lL of water? They also, in general, recommend
using a 100mM solution of NaOH to help to dissolve amino acids.

Well Soma,
I am a noob and definitely not tops in chemistry knowledge ( there is just so much  ).
I came across this web page on molar equivalents that may answer your query.

There is nothing more useless than doing well that which need not be done at all.

Wouldn't use NaOH without doing some research.
The material you are using, is the Amide of an amino-acid. That amide could be hydrolysed under basic conditions.

Your calculation is correct, if the supplier recommends 100 mM NaOH I don't see a reason not to use it. But maybe make a fresh solution every time you
need it for reasons mentioned by zed.
