(-)-(S)-1-tert-butyl-2,3,3a,4-tetrahydro-3a-methylinden-5-one - Odor description (10% DPG, blotter): woody, dry, agrestic odor with coniferous aspects and a slightly fruity, animalic and powdery tonality. Odor Threshold (GC) = 37.9 ng L–1 air = (-)-(7aS)-3-tert-Butyl-7a-methyl-7,7a-dihydro-1H-inden-6(2H)-one Ref: Felker, I., Pupo, G., Kraft, P., & List, B. (2015).

(+)-(R)-1-tert-butyl-2,3,3a,4-tetrahydro-3a-methylinden-5-one - Odor description (10% DPG, blotter): woody-musky odor reminiscent of Cashmeran with aspects of methyl ionone. The odor is less sweet, musky and fruity than that of Cashmeran, but more raspberry than apple-like in its fruity character and drier in its woody note, containing slightly rooty facets. Odor Threshold (GC) = 15.1 ng L–1 air = (+)-(7aR)-3-tert-Butyl-7a-methyl-7,7a-dihydro-1H-inden-6(2H)-one Ref: Felker, I., Pupo, G., Kraft, P., & List, B. (2015).
