Please help me to identify a chemical substance...

Please help me to identify a chemical substance. I ordered "tadalafil" substance from Chinese store but later found in description that formula is C22H23N3O3 which is not exactly tadalafil. I found some useless shit about density, weight and othe physical stuff, but nothing about pharmaceutical use.

RIGGITY RIGGITY WREECKED SON XD

Still makin' Neutrino bombs eh Rick?

Close enough faggot. If a dug is 99% similar it's basically the same thing. Stop being a pussy, man up, and take it.

>ordering recreational synthetic drugs from China
You wanna die? 'Cause that's how you die.

That is completely false.

Did you really try to order a bunch of cialis from China? There are other legal things you could buy instead that are equally effective.

Color me interested. Bumping.

It's probably made from ground up critically endangered animals. So it must be good.

>when your weed dealer never took a basic organic chem class

Kek

Chemist here,

With only the molecular formula you dont know almost anything about the compound. You need to know how is it (shape and bonding)

nigga you ordered a bunch of Cialis lmao

Not a chemist but mathematician here, isn't the question whether or not there is a structurally similar chemical without the oxygen and with the extra hydrogen that could still inhibit PDE5?

...

Any credible chinese doctor knows critically endangered animals make your dick bigger.

some scientific shit

Could be. But I wouldnt try, Honestly.

At least I wish I can take my delivery without being arrested for importing forbidden drugs

I can't imagine that there are that many possible variations that could still inhibit PDE5 and be similar to tadalafil. I understand not wanting to bother to try to figure it out, but why complain about insufficient information in the first place then?

naw you'll just a get a customs seizure letter in the mail.

Not him but molecular biologist here (though tired and high so how useful I am is up for debate). There probably is but op absolutely would not have the chemistry background to actually alter the chemical they have. Removing a hydrogen can seriously impede a lot of structural features of the molecule, as well as binding potential, and ultimately, the effectiveness of the drug. More so, removing an element that will work in hydrogen bonding and replacing it with hydrogen will significantly alter its ability to bind. Removing an oxygen and replacing it with a hydrogen also influences the size of the molecule, any cell symporters or antiporters are extremely specific to the molecule they allow through into the cell. To the point where you can see a porin allow in almost negligible amounts of Mg when it allows in calcium. For the protein, both elements have the same electron binding but the only difference is a slight shift in size.
Finally, replacing an oxygen with hydrogen changes the overall charge of the cell which may radically increase or decrease its ability to pass through cell membranes. This means it could not work at all or work too well and have higher toxicity.

The problem is that in Soviet Russia drug uses you.

One quick Google search

Thank you dude. Seems they dont want to understand,


So OK, try, If you die we ll see you on news

Many thanks. It looks like they took hydrogen and replaced it by hydrogen so it can bind while its binding

I dont complain. I only said that If you think that having a similar molecular formula gives you a similar compound with similar effects, you are wrong.

"Hey, I ordered water and I got H2S instead H2O, LETS TRY"
....

So basically, it's possible what he bought is still a PDE5 inhibitor but it's most likely that it's not. Is that accurate?

I really gotta study up on chemistry at some point. I only took the first class of the intro series when I was in school but it comes up in my life constantly.

substance is aka cialis, used for erec. dysfunction

Thanks, cap

It can be the same formula and Fuck him up. Cis-trans isomers have radically different effects. Tylenol is a painkiller and its isomer AMAP is a liver killer.
Yeah, would need a spectrometer read out of it and what he wants to really know for sure. Or xray crystalography for clearer results.

In all op, I wouldn't Fuck with it. China has some loose laws around chem labs, there's a solid chance what you got isn't even what is labelled. Make a friend in biochem, chemical eng or ochem in their masters and they might be able to hook you up with some lab grade shit.

this. i ordered coca leaf tea for laughs from columbia. all i got was a customs seizure letter. $15 shot in the ass.

I guess I was confused because a similar molecular formula can also mean a similar chemical in terms of structure and effect. It's just also possible that it has a dramatically different structure. But considering the context, that it was sold as another drug and has a similar molecular formula to it, it seemed more likely than usual that it still would be a PDE5 inhibitor but the structural difference is either for legal or manufacturing reasons. At least, that was my reasoning.

I order cialis overaseas and my doctor said to make sure I was getting it from india or UK - he said the china stuff was shit.

Why don't you just get a script for it, and order it from a "legit" online pharm instead of getting shit from china?

mine was seized for the first time this last month. really sucked. they sezed the following shipment too.

this last time, I ordered a much smaller amount ( 24 tabs vs 96 ) and they didn't seize it. not sure if that was just luck or what.

Just because it is like 20 times cheaper than pills in local store
