Aminoglycosides commercially available

Tsuji and Robertson analysed aminoglycoside antibiotics by GC of kanamycin, paromomycin and neomycin [525] and tetracyclines [526] after their silylation with a BSA-TMCS mixture in pyridine (1 1 2, v/v) or with commercially available Tri Sil Z reagent. The reaction was performed at room temperature for 24 h or at 75°C for 45 min. Good results with respect to peak symmetry and the separation of various compounds were obtained on silicone stationary phases at 260°C.
