how to calculate compound density?

[curve]

i am not in chemisty, so i need some help trying to calculate the density of 2ct-7.


2,5-dimethoxy-4-(n)-propylthiophenethylamine

I can find no references regarding the density of 2-CT-7. As regards how to find out this, you would need to determine what it is soluble in. I will assume you are speaking of the hydrochloride salt, so chances are that it is somewhat soluble in H2O - water. You could precisely weigh one gram and add it to a VERY accurately measured volume of H2O in a precision graduated cylinder and not the increase in volume. If this were to add, say, 1.5ml of volume, then your density would be 1.5.


However I fail to understand why you need this information. Are you trying to weigh the chemical using the volumetric method? If so you should measure by adding the solvent to the chemical to a given level of solvent. Example: 1 gm 2-CT-7 to a total level of 200ml H2O would equal 5mg/ml. But don't go higgeldy-piggeldy off and do this as I am not sure that 2-CT-7 hydrochloride IS soluble in water! Also keep in mind that even though it may say 1gm on the container, there is a good chance it may actually contain more or less. Always use an accurate balance to verify the weight before attempting to make a volumetric measure. Also, if using water - be sure to use distilled water from a reputable company. Not the chlorinated stuff that comes from the tap in your kitchen. Also the volume of liquids change with temperature. So if you will be storing whatever in the refrigerator, chill the solvent to this temperature before proceeding so you will have a more accurate reading.

i just dont want to spend $200 on a scale

[ChemicallyBound]

if you don't want to spend $ on an analytical scale then please don't do RC's as you are just playing roullette with your life.


Really, you spend $100 on an RC and can't go another $100 to be sure you do it right? all or none. either do it right or not at all

[curve]

i was only trying to find out the desnity so i could capsulate it. the capsulating companies go by density not just by weight, i need 30-50mg capsules.


show me where i can get a scale that measures mg for 100 and will happily buy it.

^and i will chastise and castigate - neigh, take for a public flogging - anyone who is playing with RC's and who's ass is too cheap to buy a scale.

buy a scale...Edited by: nanobrain

So $100-$200 isn't worth your life or neurological health??? Save that money by being cheap on something else that wouldn't possibly affect your life...GO GET A SCALE!!!! This is the best advice anyonewith a right mind can give you...

thank you for your input everyone.


"So $100-$200 isn't worth your life or neurological health??? "


my neurological health will not be damaged on a guessed dosage between 30 and 50mg of 2ct-7.

[nanobrain]

^famous last words. Remember Jake Duroy?

[akcom]

wasn't 2C-T-7 the one with deaths at ~35mg insufflated? Have fun doing 50mg.

[ChemicallyBound]

Curve, so there you go. if you only need to guess a dose between 30-50 mg then a $100 scale with an accuracy of 10mg is all you need since 40mg weighed can be either 30 or 50mg.


ummm... good luck, I think you'll need it.


p.s. better check make sure the insurance is up to date


p.p.s. the only reason pharms go by density is because they have accurately and precisely measured and calculated these constants on very carefully mixed compounds with UNIFORM crystals sizes. RC's do not have UNIFORM crystals sizes so you can't go by density unless you crush the crystals to a known UNIFORM crystal size

[Dimitri]

you can get even scales on Ebay with 0.001 g accuracy for about 70$.
They are not the best ones, but you should definitely do that,
man.

some of these guys really like one line'ers.


i have already tried 50mg andi would never insufflate anything


but thank you dimitri, chemicallybonded, and nagognog2 for the useful information. i did not know that the desnity was inconsistent and i will rethink my approach

i am aware of that bluemystic and i thank you.. but some of the sarcasm and comments are unnecessary in communicating that

[nanobrain]

^hurray, we mighta got through.

to add on to ChemicallyBound's info, particle size, even for the same substance, differs depending on application - micro, nano, etc.

case closed.
