“…For acylation of cocaine analytes, the haloalkylacyl derivates, particularly the fluorinated ones like pentafluoropropionic anhydride (PFPA) and heptafluorobutyric anhydride (HFBA), are widely applied to several biological matrices, like blood and urine (Aderjan et al, 1993;Cardona et al, 2006;Saito et al, 2007), and hair and tissues (Cardona et al, 2006;Jurado et al, 1995).…”

“…Due to the weak reaction of acyl derivatizing agents with carboxyl groups, most of the studies on cocaine determination using a GC method combines to the acylating agent an alkylating one, such as 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) and 2,2,3,3,3-pentafluoro-1-propanol (PFPOH) (see table 3), which easily displace the reactive proton of carboxyl groups, increasing thus the efficiency of the derivatization of all hydroxyl, carboxyl and amine functional groups (Cardona et al, 2006).…”

“…Outros trabalhos utilizando a pirólise analítica ou os produtos de pirólise para identificar a presença de drogas e seus metabólicos no sangue, na urina ou em tecidos humanos têm sido feitos [114][115][116][117][118] . Neste sentido, Mitsui et al 119 aplicaram a pirólise para estudar narcóticos e sais de alcalóides em urinas de seres humanos.…”
