Save your unusable raws Guaranteed.

@janoshik

if theres solvents left after doing recrystallization on raws and sending them to you

do you reckon gcms or hplc will pick it up? i remember ive seen you put it in the comments even in hplc before but would be better for you to clarify so we know what testing to go ahead and do? especially since the solvents are pretty different from normal steroid molecule it should be pretty easy to pick up

thank you for time.

Ah yes, the good old residual solvents methods I was shit on repeatedly for bringing up. Funny how we are coming full circle.

You can search here.

Jano doesn't have a method last time we discussed. Perhaps now there will be a driving force to develop one.

Sounds pretty stupid to shit on that idea. All the manufacturers have to recystalize the product at some point and im sure they are using harsh solvents. Sounds reasonable to me to test for it

It aged well.

we keep running into the same fucking problem.

readalot tries to help the community = gets hate

most other guys does stuff for ourselves including me = no hate

readalot has to realize fak the community and just chase his self intererests.

these redacted get mad at not understanding so its better to not engage in advanced topics with them

Gym bro, keyboard warriors are the demise of anything constructive...

Thanks for everything @readalot !

 

[mongo5165]

I appreciate @janoshik passion for correctness and precision, but man we need a method for testing this stuff..

I was doing test cyp and test e, not sure why no ester would effect the solubility that much. I ran it through grok and its saying 150mg/ml for TNE when heated. It will probably make recrystilization that much easier.

Probably this lol

155 C... yikes..

The last time i believe Scholar used acetone.
He sent it for GCMS and then concluded it was not present and thus his process was gtg.


TLDR Acetone cant be detected

I actually won't be surprised if AASRaws is doing that now..
They delayed their shipments and sent it back to the factory for "reprocessing".

Really enjoyed reading your crystallization clinic in this thread @mongo5165. Thanks for taking the time to share all your efforts with the group!!

at my work they have full internal qc testing.

but im also doing a routine of checks.

one include something we can use for residual solvents called loss of drying.

just when you dry your raw under vacuum you just measure its weight before and after until it dosent change anymore. if the weight drop is less than 0.5% it suggests its g2g low residual solvents for, although not guranteed

Yep, Jano can do that. Demonstrated in prior project. Nice setup he has.

it also makes math easier

0.5% or 0.05ml per 100mg api. assuming atleast 90% of what visible solvents get removed. we can use around 4.5ml solvent per 100mg api. solvents removed is probably higher tho

Example. Would need to make sure raws don't pick up water and register false positive for RS. So could also do KF titration to check.

my math is off, its 4.5ml ethanol per 100mg api edited it which is plenty

i thought that iris girl were into rektest but apparently she into u lmao

Nevermind, forgot why the dry mass was so low on that test. Would need to revisit.

Could check with Jano if we could rework the screen.
