For tablets “Malоben, 60 mg” and “Etmaben, 300 mg”, permission was received to conduct phase I clinical trials, so they required a full cycle of research and standardization.</p></sec><sec><title>Aim</title><p>Aim. Development of a unified analytical procedure for the determination of related impurities in samples (RS, API, FPP) of Malоben and Ethmaben.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. RSs were obtained at the Department of Organic Chemistry of the St. Petersburg State Chemical and Pharmaceutical University; the synthesis of APIs and the production of FPP were carried out on an industrial scale in pharmaceutical production. The studies were carried out on a Flexar liquid chromatograph (PerkinElmer, USA), equipped with a pump (formation of a gradient on the low-pressure side), an autosampler, a column thermostat, a UV detector and a chromatographic column Intersil® ODS-3V, 5 µm, 100 Å, 250 × 4, 6 (Phenomenex, Japan).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. In the research, uniform optimal chromatographic conditions were selected using the HPLC method to determine the RP in RS, API and FPP of Maloben and Ethmaben. Column C18 250×4.6 mm, mobile phase 0.1% phosphoric acid and acetonitrile (gradient elution), flow rate 1 ml/min, sample volume 10 µl, UV detector (270 nm). They were validated in terms of specificity, linearity, detection limit, precision, robustness, and solution stability. Analytical concentration levels were selected for the formation of draft regulatory documents. Using the developed analytical technique, samples of RS, API and tablets of malоben and ethmaben were analyzed.</p></sec><sec><title>Conclusion</title><p>Conclusion. A full cycle of research was carried out, an analytical methodology was developed and related impurities were identified in RS, API and FPP of Maloben and Ethmaben.  </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сквозная стандартизация</kwd><kwd>оригинальные ЛС</kwd><kwd>родственные примеси</kwd><kwd>ВЭЖХ</kwd><kwd>валидация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>end-to-end standardization</kwd><kwd>original drugs</kwd><kwd>related impurities</kwd><kwd>HPLC</kwd><kwd>validation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Результаты работы получены с использованием оборудования ЦКП «Аналитический центр ФГБОУ ВО СПХФУ Минздрава России» в рамках соглашения № 075-15-2021-685 от 26 июля 2021 года при финансовой поддержке Минобрнауки России.</funding-statement><funding-statement xml:lang="en">The results of the work were obtained using equipment the Сore Shared Research Facilities «Analytical Center» of the Saint Petersburg State Chemical and Pharmaceutical University, with financial support from the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15-2021-685; dated 26 July 2021 on the provision of the Federal budget grants).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Graham J.
