Optimization of HPLC chromatographic conditions for determination of Transkarbam 12 and its degradation products.

This paper deals with searching of HPLC chromatographic conditions for determination and separation of Transkarbam 12 (T 12) and its two main degradation products (omega-aminocaproic acid and dodecylalcohol). T 12 is a new substance which belongs to the group of accelerators of transdermal penetration. Chromatographic separation was achieved using Separon SGX C18 analytical column (150mmx3mm i.d.; 5mum). Mobile phase contained acetonitrile and sodium acetate buffer pH 4.5 at the flow rate of 1ml/min. Separation was carried out under the conditions of gradient elution. After the modification of the structure by derivatization reagent (3,5-dinitrobenzoyl chloride) detection at wavelength 230nm was realized. The aim of this study was not only the optimization of the separation of derivatization reagent and derivatized T 12, Ak and D but also optimal derivatization processes for all three substances.[1]
