| Abstract: | A HPLC method with amperometric and coulometric detection for the determination of SZ1677 and its two derivatives SZ1676 and SZ1823 has been developed. This active substance is under development (clinical trial) and there are no analytical methods published for the determination of SZ1677 thus far. The limit of quantitation for SZ1677 was 25 and 100ngml(-1) by the coulometric and amperometric detection, respectively. The elaborate method for the simultaneous analysis of SZ1677 and its two derivatives proved to be fast, precise, accurate and sensitive. |
