There are two calculations you need. What calculations do you know of for calculating concentration? Or, what units is concentration usually expressed in (hint: what does mM mean?)

If it's for a legitimate research purpose, you could try and email the contact on the clinical trials. I do not think this compound or your other one would have an actual supplier. Most likely they are synthesised by the pharma companies running the trials, or by a group they collaborate with. Unfortunately, you having a particular disease would not be a legitimate research purpose. This is what clinical trials are for. Again, you could try and contact the person listed in the clinical trial documentation (you can find this online), but I would not hold out much hope.

No company will synthesise a chemical for you for consumption a purposes if it isn't already approved by whatever drug administration board. Sorry, but you're out of luck here.

I suspect, though cannot substantiate, that many of the people with $1000 or less are not people with much of a choice in the matter.

Why are you looking to purchase these?

It's incredibly unlikely that there is a supplier for this, as it doesn't have any commercial value as yet due to it only being at the clinical trial phase. Why do you want it?

I'm actually not sure who runs the IRC anymore. The person who used to host it sadly passed away late last year, and I cannot recall what happened to it after that. There are people active here who frequented some of the other channels who might know.

I should also point out that it isn't Ag(NH3)2, it's [Ag(NH3)2]+. You would be making the nitrate salt in this case, aka Tollens reagent. I don't know of a good way of purifying this as it is not really my area. A thought has occured to me that might help, but I'd first like to know if you're making the NP for the purposes of consuming them or what?

You should have made that more clear in your OP. The amounts of reagents you need to add is really something you should figure out as part of your experimental procedure. Where did you get your method from exactly that you don't already have this information? Do you know what happens when you add the hydroxide? What does the reaction look like? As for your last question, you can't really do a reaction to produce a specific and precise concentration of product in this way, because it depends on the yield of the reaction and any number of other variables. You can make an educated guess based on stoicheometry and assuming quantitative yields and that you don't have any Ag2O left, however. This relies on you knowing the reactions involved, and on whether or not the other things in the solution are going to be problematic. Regardless, and with respect, you don't really seem equipped to be making things that are potentially quite explosive. What is this for?

Are you familiar with calculations used to work out concentration and number of moles? There are two that concern you: concentration (moles/litre; often written as M) = number of moles / volume (litres) Number of moles = mass (grams) / molar mass (grams/mol) These are all you need, in addition to working out the molar mass of your compound (this is easily searchable).

That's sort of what I thought. And yes, parrots do sneeze! It's actually kind of cute.

The bird was sick first, yes. As far as I know, their vet is positive it is Streptococcus pneumoniae. I believe they did culture tests of some sort from a crop swab. It doesn't really matter, and I think the person in question is getting tested, I was more just curious to know if it were possible to catch said infection from a parrot (or other animal). She seemed absolutely positive that you could. I wasn't so sure, and to date she has been extremely evasive when I've asked for where her information came from. I know that there are other infectious diseases that you can get from parrots, the big one being psittacosis (from Chlamydia psittaci), but I had thought this was a pretty unique case.

Thanks to both of you, your posts were very helpful. The discussion that prompted this was actually about a parrot that had tested positive for an S. pneumoniae infection. The owner of said parrot mentioned that she had been quite sick, with persistent symptoms for some time (after the bird's symptoms began). She thus concluded that she might have become infected with the same thing, presumably via her bird, and is pushing her doctor to get tested for it. This seemed (and still sort of does seem) pretty unlikely to me, but I wasn't sure exactly if my instincts on that front were correct. It is complicated by the fact that research into parrot diseases and the like is pretty sparse. Most of what we know and rely on about their care as pets comes from research into chickens, which is not super reliable.

As per the title. I searched Google and Google scholar briefly, but I was unable to find anything conclusive. I came across some people on another forum who claimed that it absolutely was, but I am not completely convinced.

Do you have access to a controlled vacuum? You could vacuum distill the DCP off with mild heating. Strange that ion exchange resins didn't work though. What were you using?

Even ignoring all of the great points outline by Function, culturing human cell lines is notoriously difficult, even in the most experienced of labs. It's not something you can just do with a petri dish.

Could you possibly give some more detail on the desired product? Why is the energy requirement for evaporation too high?

! Moderator Note It seems half of the posters in this thread have forgotten that we have rules regarding civility and insulting other members. Those members may consider themselves officially warned. Tampitump, while the trolling isn't necessarily against the rules, your subsequent posts most certainly were. You have been suspended for 1 year. Everyone else, stick to the topic, and stop the insults. It won't be tolerated.

! Moderator Note Mike, your focussed argument is just more waffle. We're not going to tolerate another 20 page thread of complete nonsense on your part, so I'm closing this pending review.

! Moderator Note Yes, and being as this is a science forum, we have rules regarding the scientific rigour expected of the posts here. Perhaps you should read them. http://www.scienceforums.net/index.php?app=forums&module=forums&section=rules&f=29 Specifically: 'Speculations must be backed up by evidence or some sort of proof. If your speculation is untestable, or you don't give us evidence (or a prediction that is testable), your thread will be moved to the Trash Can. If you expect any scientific input, you need to provide a case that science can measure.'

Whoever told you that is speaking nonsense. There is plenty within biology that some degree of applied math is useful in, such as bioinformatics (which incidentally, is a relatively employable area to be in). If you had to choose one from the list, I'd go with the last one.

Oh, sorry. It's possibly oversimplified. I don't think the geometry really favours intramolecular hydrogen abstraction, but overall you are essentially seeing the acidic proton of the acid moving to the nucleophilic oxygen (on the right). This drives the formation of another C=O (on the left), and the breaking of the other C-O bond. This isn't the exact same sort of molecule, but is illustrative of an analogous mechanism.
