Odor Type: Green
green, leafy, nutty
General comment	At 0.10 % in dipropylene glycol. green leafy nutty
As with all pyrazines this is used in tiny traces Leafy Pyrazine at 0.1% in DPG is quite nutty-brown smelling but on further dilution a green and leafy odour is realised. Mainly used in flavour work it can add original green notes to fragrance Even at this dilution this is a strong material that can enhance or contribute to green notes, diffusion and naturalness.	Green-leafy, grass, natural, nutty
