MS of 5 and 6 APDB
where is the promised mass spectrum for 6-APB?
for reference these are the dihydro compounds. Neither as expected shows the molecular ion. but show 44 as the base peak (diagnostic for amphetamines)
6-(2-aminopropyl)-2,3-Dihydro Benzofuran,
1-(2,3-dihydrobenzofuran-6-yl)propan-2-amine
m/z (abundance)
44(100) , 134(72) 133(22) 77 (9)
5-(2-aminopropyl)-2,3-Dihydro Benzofuran
1-(2,3-dihydrobenzofuran-5-yl)propan-2-amine
m/z (abundance)
44(100) , 134(62), 133(20), 77(7), 135 (6) 91(6)
retention time slightly less for 1-(2,3-dihydrobenzofuran-5-yl)propan-2-amine but not significant enough It is therefore impossible to tell the 5 compound from the 6 compound with GC-MS alone.
also mass spectrum of authentic (genuine) 5-APB and 6-APB has been obtained.
