Description and usage notes:
Can be used in perfumes only in traces to add realism to gourmand and especially seashore types.
Arctander suggests the main uses of pyridine relate to coffee and chocolate, as it forms a key part of the aroma of both.
The odour isn’t, in the opinion of this perfumer, as repelent or as powerful as the widely circulated descriptions would suggest.
As such we are offering pyridine at 1%.  We also offer this material at 50% in DPG for those who work in larger quantities.

DH (verified owner) –
I’m probably just odd, but I actually found this “extremely powerful” material difficult to detect. Diluted down to 0.1% all I get is maybe 30 seconds of something very mild, vaguely matching the given description. I will come back to it again and see if I can smell it better in time.
