from what I gather, the picture is a bottle of PG
Sorry BK but, you seem to have a hard time following the flow of the thread.
Someone told the OP that they doubted that Merck would sell directly to the public and they doubted that the retailer that they had bought from was actually able to sell them Merck products. The OP posted the pic to show that the bottle of PG that they had bought was branded Merck. Did you even read the text that you quoted with the pic?
If you check the badly copy/pasted info in the OP you will see that a couple of the things posted about the product in question are:
Synonyms
3-(1-Methyl-2-pyrrolidinyl)pyridine, (S)-(-)-Nicotine
CAS number
54-11-5
EC index number
614-001-00-4
This same info, along with everything else in the OP, matches the info in the link I posted but the link has more including:
Assay (GC, area%)
≥ 99.0 % (a/a)
I don't understand why you continue to press the issue? If someone has a bottle of nic from a pharmaceutical company that says 99% on the label, what difference does it make if you believe it to be 99% pure or not?
ETA: Also, from a safety point of view, telling someone that their 99% bottle of nic is 10% is erring on the side of recklessness. Pretty sure that was not your intention.
