Sharaxaad:
n-Heptane waa dareere cad oo aad u guban kara oo isbeddeli kara oo leh ur khafiif ah oo u eg gaas. Heerka urta waa 40-547 ppm; sidoo kale waxaa lagu soo warramey 230 ppm. Miisaanka molecular = 100.23; Cuf-isjiidadka gaarka ah (H2O:l) = 0.68; Barta karkarinta = 98.39C; Barafka dhalaalka = - 90.6℃; Cadaadiska uumiga = 40 mmHg at 25℃; Barta iftiiminta =一4℃; Heerkulka iswada = 204℃.285℃. Xadka qaraxyada: LEL= 1.1%; UEL= 6.7%. Aqoonsiga Khatarta (ku salaysan Nidaamka Qiimaynta NFPA-704 M): Caafimaadka 1, Dab-shidka 3, Falcelinta 0. Ku dhawaad aan ku milmi karin biyaha; milmida = 0.0003%.
