Sumformula of the chemical :
C7H14O2
EINECS-number :
2110473
 
Uses :
Solvent.
 
Odor :
Characteristic.

Quality: sweet, ester, banana.

Hedonic tone: pleasant.

Odour index: 25.047
(Hellman & Small 1974).

Threshold: unadapted panellists: 20 ppm
           after adaption with pure odourant: 3000 ppm

Human odour perception: non perception: 0.5 mg/m3
                        perception    : 0.6 mg/m3 = 0.11 ppm
human reflex response : no response: 0.12 mg/m3
                        adverse response: 0.30 mg/m3
(Stern 1968).

1800  at 20 °C
 
Boiling point, °C :
148  at 737 mm
149.3 
 
Volatilization :
Relative volatility (nBuAc=1) = 0.42
 
Other information of degradation :
Impact on biodegradation processes:
Inhibition by degradation of glucose by Pseudomonas fluorescens at
350 mg/l; inhibition of degradation of glucose by

  --
650  srv, act, 96 hr, Lepomis macrochirus,
180  srv, act, 96 hr, Menidia beryllina
  Dawson et al. 1977
