Sodium Bisulfate adduct of Benzaldehyde QUESTION

I made this compound and was wondering if anyone here has a MSDS for this and possibly some photos of the crystals to compare to my results.

Just how are photos supposed to help you in any way? A white crystalline powder looks just like any white crystalline powder.

You can characterize it by derivatization. For example, you can decompose it to benzaldehyde and identify this by one of the classical methods, bp measurment being the easiest. Alternatively, you can derivatize it to its 2,4-dinitrophenylhydrazone or semicarbazone and measure their mp.

Why do you need its MSDS? It is not particularly toxic and can be handled without worries. Just make sure you don't ingest any.

PS: Please open threads without references only in the Beginnings section.

I do not have a melting point apparatus at this time my old one burn out. I was asking for some photos to compare the shape and color of the crystals, as this is the first time I have made this from the bitter oil of almond extract. I will convert it back to benzaldehyde as you say. Thanks for the input.
