2 I. Identity The identity of the reference substance was established by following analyses. Ia. 1 H-NMR Spectrum Conditions: 400 MHz, DMSO-d 6 The structure is confirmed with the signals of the spectrum and their interpretation. LGC GmbH, Im Biotechnologiepark, TGZ II, D Luckenwalde, Germany page 2/6

3 Ib. Mass Spectrum Method: EI, 70eV, detector temperature: 280 C m/z Fragments (M = free base) 221 [ M ] 204 [ M NH 3 ] 153 [ M C 4 H 4 O ] The signals of the mass spectrum and their interpretation are consistent with the structural formula. LGC GmbH, Im Biotechnologiepark, TGZ II, D Luckenwalde, Germany page 3/6

4 Ic. IR Spectrum Method: Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) Spectroscopy The signals of the IR spectrum and their interpretation are consistent with the structural formula. II. Purity The purity of the reference substance was analysed by high performance liquid chromatography (HPLC). HPLC Conditions: Column: Conditions: Detector: Injector: Hypersil Gold (C18) 1.0 ml/min, 40 C DAD Auto 5 µm, 150 x 4.6 mm 0-6 min Water/Acetonitrile 90/ min Water/Acetonitrile to 50/ min Water/Acetonitrile to 90/ min Water/Acetonitrile 90/10 (v/v); 0.1 % H 3PO nm 3 µl; mg/ml in Water LGC GmbH, Im Biotechnologiepark, TGZ II, D Luckenwalde, Germany page 4/6

5 400 PDA_7-215nm Retention Time mau mau Minutes Area Percent Report - Sorted by Signal Pk # Retention Time Area Area % Totals For the calculation the system peaks were ignored. The content of the analyte was determined as ratio of the peak area of the analyte and the cumulative areas of the purities, added up to 100 %. Results: Average % Number of results n=3 Standard deviation 0.01 % LGC GmbH, Im Biotechnologiepark, TGZ II, D Luckenwalde, Germany page 5/6

6 III. Water Content Method: Karl Fischer titration Results: Average 0.05 % Number of results n=3 Standard deviation 0.02 % IV. Residual Solvents Method: 1 H-NMR No significant amounts of residual solvents were detected (< 0.05 %). V. Final Result Total impurities (HPLC) 1.47 % Water content 0.05 % Residual solvents n. d. (not detected) Assay (100 % method) % The assay is assessed to be 98.5 % as is The assay 'as is' is equivalent to the assay based on the not anhydrous and not dried substance respectively. 1 The calculation of the 100 % method follows the formula: Assay (%) = (100 % - KF - RES) * Purity HPLC (%) 100 % Water (KF) and Residual solvents (RES) are considered as absolute contributions, HPLC purity is considered as relative contribution.
