Aren't they something you use to grow that third hand you need to put a clearomizer back together after cleaning? 
Just sayin...
Way over my head, although someday I hope to be educated enough in e-juice chemistry to understand their use.
I give you a lot of credit to have advanced to this point!
Kudos to you!

Acetyl Pyrazine :
taste description:
at 10.00 ppm. Roasted, nutty, bready and yeasty, with popcorn and corn chip nuances
good for graham gracker flavors (enhancer)
Mosciano, Gerard P&F 17, No. 1, 41, (1992)
CAS # 22047-25-2
FEMA # 3126
can use up to 10.0000 ppm in the flavor. (refers to the undiluted material)
I have used this in certain recipes and can tell the difference...enhanced the overall recipe...
Trimethyl Pyrazine:
heart/mid note
nutty musty earthy powdery cocoa roasted peanut
Tase Description: Raw, musty, nutty, potato
Mosciano, Gerard P&F 15, No. 6, 35, (1990)
CAS # 14667-55-1
FEMA # 3244
can use up to .1% of total fragrance concentrate
use up to 80 ppm in flavor (undiluted)
haven't tried this yet...
Linalool:
a good general builder - floral - appears in all types of compositions from floral to citrus
CAS # 78-70-6
FEMA # 2635
can use up to 12% of total fragrance concentrate
taste description:
at 10.00 ppm. Citrus, orange, lemon, floral, waxy, aldehydic and woody
Mosciano, Gerard P&F 21, No. 1, 33, (1996)
for flavors, try using this at a 1% dilution
haven't tried this yet either...

Perfumers Apprentice has descriptions for these:
Linalool
Acetyl Pyrazine
Trimethyl Pyrazine
Perhaps you've already seen these descriptions? But one thing that stands out to me is that they are incredibly strong. The doses they give in parts per million (PPM) are for making flavour concentrates (which you could then dose at a suitable level in e-liquid) not e-liquid itself. Personally I'd stick with concentrates unless I really felt experimental.
EDIT just to add I've seen all of these ingredients listed on pre-mixed e-liquids that show their ingredients on the bottle (normally Chinese liquid) so they are all used in making specific flavour "notes" but I don't think any one of them would be considered a flavour in itself.

no need to say sorry, Debb! I appreciate your reply. 
I was just answering a question asked by Papa if I had seen/read them.
I'll call Linda tomorrow to get some input on their mixing usage.

let us know what you find out..
The problem is this "10 ppm" stuff doesn't translate well into drops and ml. How much of a 5% solution do you add to get it?
And in the case of the 5% Acetyl Pyrazine solution sold by TPA, even a single drop amounts to way more than 10ppm for most batches people would work with.
The answer is to dilute what they have sent even further for ordinary use.
What you do is dilute it sufficiently that 1 drop (figuring 25 drops per ml) would amount to 5ppm in a 10ml batch, so if you wanted 10ppm you'd use 2 drops. This give you a bit of flexibility.
I'm not sure if you want me to skip the math and just give the answer.
Bear with me while I do the math.
How much does 5ppm of 10ml of water weigh? It is 5 millionths. Divide 10g (1ml of water weighs 1g) by 1,000,000 and multiply by 5. The answer is .00005g. So we want each drop to contain .00005g of Acetyl Pyrazine.
One ml of 5% Acetyl Pyrazine contains .05g, and one drop contains .002g.
To make 6ml of solution such that each drop contains .00005g, the entire bottle should contain .00005g x 25 drops x6 = .0075 g. That's close enough to .008 g for government work.
So what you do is take an empty 6ml squeeze dropper bottle (available ubiquitously from diy suppliers), add 4 drops of the 5% Acetyl Pyrazine solution (which will give you 4 x .002g), and then fill it the rest of the way with propylene glycol.
Now, every drop of this solution that you add to a 10 ml batch of ejuice gives you approximately 5 ppm of Acetyl Pyrazine.
This same technique will work for any of the 5% solutions sold by TPA. Just put 4 drops in a 6ml dropper, fill it the rest of the way with PG, mix thoroughly and shazam -- you now have 5ppm (or close enough anyway) per drop when added to 10ml of ejuice.
So to get 10ppm you add 2 drops.
If you are making 5ml batches, 1 drop would be 10ppm.
If you are making 6ml batches, 1 drop would be about 8ppm.
I demonstrated the technique so it can be modified for different concentrations and batch sizes.
Note: I've simplified things a little bit because PG doesn't weigh the same as water etc. But we are making flavors rather than explosives so the benefit of clarity is IMO more important than the absolute accuracy that would come from modifying for the density of components and correcting for standard temperature and pressure, etc.

On trimethyl pyrazine ... it comes in a 10% solution and should be used at concentrations no greater than 80ppm.
Lets make it so that each drop is 10ppm in a 10ml solution. That way, 8 drops would be the maximum used and you'd have a lot of room to play.
So ... we want each drop of our final solution to contain ... 10gx10/1,000,000 = .0001 g of Trimethyl Pyrazine.
As it comes, each drop of the 10% solution contains .004 g.
A 6ml container would need to contain a total of .0001 g/drop X 25 drops/ml X 6 ml = .015g
.015g/.004g per drop = 4 drops
So, add 4 drops of this to a 6 ml container, fill it the rest of the way with PG and shake well. Each drop will amount to 10ppm in a 10ml batch of e-juice, so you can use up to 8 drops.

As for the linalool ... I am not clear from the description on the tpa website how concentrated the solution they are selling is, so I have no idea how to dilute it.
Hopefully, though, you have found this helpful!

per Linda, linalool is strong and is not diluted.
The other two she said are diluted in PG.
Very good! As their data specified 10ppm when used as a flavoring, then we can do like this ...
Assume it is 1gm per ml, which means 1gm/25 drops = .04g per drop
If we want some flexibility, we should make it so it yields 2.5 ppm per drop when added to a 10ml batch. 1ppm for 10ml = .00001g, so 2.5ppm = .000025 g
So the total amount we need in a 6ml bottle is .000025g/drop x 25drops/ml x 6ml = .00375 grams
Okay ... so this is a problem because even a single drop of the linalool in 6ml is about ten times too much. So we have to dilute that in a LOT of PG. Let's try 30 ml because thats a common size used by DIYers:
.000025g/drop x 25drops/ml x 30 ml = .01875
This is about half of a drop. At this point I say -- cheat and use one of those nifty disposable mini pipettes from TPA that gives you 40 drops per ml. Thats because 1/40 = .025.
So, if you put one of those 40drops per ml drops of linalool in 30ml of PG ... each regular (25 per ml) drop will contain .000033 g of linalool.
That's more than we wanted -- it gives you 3.33 ppm of linalool per drop in a 10ml portion, so the maximum you should use is 3 drops. But you could dilute it more - say, in a 100 ml container, etc.
Hopefully this is useful, and I'm happy to help!
Linda said these are advanced flavor enhancers. once diluted, use as other flavorings are used.
I think I will take all of the info, and once they are diluted...use them starting at .5 or 1% to start with in my e-liquid mixes. Does that sound safe and reasonable?
I rarely mix a 30ml btl of e-juice since I started DIY'ing. Normally mine are 3, 5, and 10ml (finished e-juice).

According to wikipedia, inhaling linalool can reduce stress in lab rats. I'm a pack rat, so maybe it'll work on me. But what I'm really wondering is just what kind of stress is a lab rat under? I mean, aside from being forced to vape linalool?
Anyway, I'd be interested in hearing if it makes for a more relaxing vape.
