I did not wrote anything from your post!

Yep. Arkcon just emptied his output. It has (mostly) nothing to do with you.

I just needed a help, because I can't find literature, sorry cause I asked!

Well, you were listed many papers so you have received help. Problem is, we can't send you these papers, as it will be against law.

Borek: is absolutely right, I don't mean what I said specifically to you.

Well, this is also true.  Did you not know this?  When I sent you to Wikipedia, for general concepts, did you think I was missing your point?  I wanted some more specifics, about what you knew, and what you needed.

What do you think of AWK:'s contribution?  In my day, we used to have to browse the indexes, in a big orange book, to find out which journals, then go through the journals.  Although, computer databases, on CD-ROM searchable by keyword, and printed out on dot matrix did arrive towards the end of my time at university.  What he went and got for you, was, in fact a magnificent time saver.  But you just want hotlinks?  To internet papers?

I need some help. :(

If you have some links about phenylosazone D-glucose, everything you can found about this chemical compound... Structure, Synthesis, Reactions, pictures, Side effects, .

Thank you!!!

We've got smileys galore, but no sign at all of work.  Do you even know what this is?  You're not going to synthesize a pharmaceutical, and self-medicate are you?  You just want everything: structure, synthesis, reactions pictures side effects, just done?  We gave you hints, and all we get are, "Not good enough"?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Before I gave references, I searched internet. Frankly saing this subject in internet is completely neglected, even in Wikipedia. Good organic textbook gives more information on phenyosazones than can be find freely on internet.
My links was selected to the most popular journals over the world. I think even a poor country have at list one substcription to this journals
(eg. the bigest university in the country, library of Academy of Sciences).

Me too.  I was curious about the application myself.  So I Googled "phenylosazone d-glucose", and didn't find anything.   Then I tried "phenylosazone" without much success either.  Only when I broke the name down, and tried "osazone" did I get the Wikipedia link I quoted.  I found enough in the Wikipedia entry to learn what the compound meant - it's a chemical derivitive used to determine chirality, back in the 1800's, highly colored, perhaps useful, as pre-derivitization reagents for carbohydrate chromatography.

Yeah, I though I said that, perhaps not as politely as I should have.

AWK: You've neglected almost all of these topics, let's go, let's go, the paper's deadline gets ever closer, c'mon, the side effects are needed right away, even 'though this is probably not a therapeutic.  And take some pictures of the chemical in a tube and post them.  Structure and synthesis are in my link, but that's not at all adequate --

Thanks, but I need more details...

Žalostan, but you'll have to check the library.

I think all this problem are showed in my previous links.
But I am adding a few more below

Osazones are not specially exciting compounds except their using by Fisher for correlation of hexoses structures. Moreover they can be oxidized to 1,2,3-oxotriazoles (osotriazoles, osones) using various oxidizers
