An accurate, sensitive and selective reversed-phase micellar liquid chromatographic method was developed for simultaneous determination of benzyl alcohol and benzaldehyde. This method was applied in different injectable formulations containing diclofenac, piroxicam. lincomycin and clindamycin. The method showed excellent linearity in the range of 10100 and 120 μg mL1 with the limit of detection (S/N = 3) 0.25 μg mL (2.3 × 106 mol L1) and 0.12 µg mL1 (1.13 × 106 mol L1) for benzyl alcohol and benzaldehyde, respectively. The suggested method was successfully applied for the analysis of the studied drugs in bulk with average recoveries of 100.1 ± 1.0% for benzyl alcohol and 100.4 ± 1.6% for benzaldehyde and to the determination of benzyl alcohol and benzaldehyde in injectable formulations with the respective average recoveries of 99.8 ± 0.3 and 100.0 ± 0.4%.Razvijena je točna, osjetljiva i selektivna reverzno-fazno micelarna kromatografska metoda za simultano određivanje benzilnog alkohola i benzaldehida. Ta metoda je primijenjena u injekcijskim pripravcima diklofenaka, piroksikama, linkomicina i klindamicina. U koncentracijskom području 10100 i 120 μg mL1 postignuta je izvrsna linearnost s granicom detekcije (S/N = 3) 0,25 μg mL1 (2,3 × 106 mol L1) i 0,12 µg mL1 (1,13 × 106 mol L1) za benzilni alkohol, odnosno benzaldehid. Metoda je uspješno primijenjena za analizu benzilnog alkohola i benzaldehida kao čistih supstancija s analitičkim povratom 100.1 ± 1.0% za benzilni alkohol i 100.4 ± 1.6% za benzaldehid te za određivanje benzilnog alkohola i benzaldehida u injekcijskim pripravcima s analitičkim povratom 99.8 ± 0.3 i 100.0 ± 0.4%
