Anwendungen & Verwendung
Beschreibung
This alkyl-substituted Pyridine has been suggested for usc in perfume compositions of the non-floral character. It blends excellently with Oakmoss and Vetiver, the earthy-mossy notes of which it will support and modify in a pleasant manner, and it produces new shades of Fougere with Amylsalicylate, Cedarwood, Lavender, Amylvinylcarbinol etc.
