Методика основана на дериватизации цианата метиловым эфиром антраниловой кислоты с последующим образованием бициклического производного (1-H,3-H-хиназолиндиона), которое обладает способностью к флуоресценции. Исследована возможность применения данной методики для определения цианата калия в белковых препаратах. Изучено влияние вспомогательных веществ субстанции на получаемые результаты. Проведена валидация методики по характеристикам: специфичность, линейность, правильность, прецизионность, предел количественного определения.</p></abstract><trans-abstract xml:lang="en"><p>Method of determination of potassium cyanate in carbamylated darbepoietin alpha drug substance was developed. The method is based on derivatization of cyanate by methyl ester of anthranilic acid followed by formation bicyclic derivative (1-H,3-H-quinazolinedione), which is able to fluorescence. Application of this method to determine potassium cyanate in protein drugs was investigated. Interference of excipients on this method was evaluated. The validation was performed: specificity, linearity, accuracy, precision, limit of quantitication.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цианат</kwd><kwd>метилантранилат</kwd><kwd>дериватизация</kwd><kwd>флуориметрия</kwd><kwd>дарбэпоэтин</kwd><kwd>карбамилированный дарбэпоэтин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyanate</kwd><kwd>methyl anthranilate</kwd><kwd>derivatization</kwd><kwd>fluorimetry</kwd><kwd>darbepoietin</kwd><kwd>carbamylated darbepoietin</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">10 ведущих причин смерти в мире.
