Использование дейтерированных аналогов исследуемых веществ в качестве внутренних стандартов позволяет определять остаточные пестициды в лекарственном растительном сырье в следовых количествах методами газовой и жидкостной хроматомасс-спектрометрии. Таким образом, становится актуален вопрос доступного синтеза дейтерированных стандартов для расширения готового банка стандартов отечественного производства.</p></sec><sec><title>Цель</title><p>Цель. Синтез дейтерированных внутренних стандартов  — малатиона-D6, хлорофоса-D6 и дихлофоса-D6. Определение спектральных характеристик полученных соединений с помощью 1Н, 2Н, 13С и 31Р ЯМР-спектроскопии и масс-спектрометрии высокого разрешения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Использовали метанол-D4, фосфора пентасульфид, треххлористый фосфор, диэтиловый эфир малеиновой кислоты, триэтиламин, гидрохинон, хлоральгидрат. Спектры ЯМР 1Н, 2Н, 13С и 31Р записаны на ЯМР-спектрометре QONE AS400 при температуре 298 °К на частотах 399,83; 61,38; 100,55 и 161,85 МГц соответственно. Регистрация масс-спектров проведена на аналитической станции, состоящей из жидкостного хроматографа Agilent Infinity 1260, оборудованного системой автоматического ввода пробы, с масс-селективным тандемным анализатором высокого разрешения Thermo Scientific Orbitrap Fusion Lumos, в режиме электрораспылительной ионизации.</p></sec><sec><title>Результаты</title><p>Результаты. На основе разработанных ранее методик синтеза фосфорорганических пестицидов определены пути синтеза их дейтерированных аналогов малатиона-D6, хлорофоса-D6, дихлофоса-D6. Подлинность синтезированных соединений подтверждена методами ЯМР-спектроскопии и масс-спектрометрии высокого разрешения.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные соединения характеризуются высокой чистотой и пригодны для использования в качестве внутренних стандартов при определении фосфорорганических пестицидов в лекарственном растительном сырье.

Deuterated analogues of test substances, when used as internal standards, enable analysts to determine traces of residual pesticides in a medicinal plant raw material by gas or liquid chromatography coupled with mass spectrometry. This prompts the search for an undemanding method for the synthesis of deuterated reference standards, with the ultimate goal of expanding the range of reference standards produced in Russia.</p></sec><sec><title>Aim</title><p>Aim. The study aimed to synthesise deuterated reference standards (malathion-D6, chlorophos-D6, dichlorophos-D6, and their precursors) and determine their spectral characteristics using 1Н, 2Н, 13С and 31Р nuclear magnetic resonance (NMR) spectroscopy and high-resolution mass spectrometry.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study involved methanol-D4, phosphorus pentasulfide, phosphorus trichloride, maleic acid diethyl ether, triethylamine, hydroquinone, and chloral hydrate. The authors recorded 1H, 2H, 13C, and 31P NMR spectra using a QONE AS400 NMR spectrometer operating at a temperature of 298 °K and respective frequencies of 399.83, 61.38, 100.55, and 161.85  MHz. Mass spectra were obtained using an analytical system comprising an Agilent Infinity 1260 liquid chromatograph equipped with an automatic sample injector and coupled with a Thermo Scientific Orbitrap Fusion Lumos high-resolution mass-selective tandem spectrometer operating in electrospray ionisation mode.</p></sec><sec><title>Results</title><p>Results. The authors used existing methods for the synthesis of organophosphate pesticides as a basis and developed synthesis routes to produce the deuterated analogues malathion-D6, chlorophos-D6, and dichlorophos-D6. The synthesised compounds were identified by NMR spectroscopy and high-resolution mass spectrometry.</p></sec><sec><title>Conclusions</title><p>Conclusions. The synthesised compounds are highly pure and suitable for use as internal standards in the determination of organophosphate pesticides in medicinal plant raw materials. The synthesis methods developed by the authors can be used to produce reference standards in Russia.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фосфорорганические пестициды</kwd><kwd>лекарственное растительное сырье</kwd><kwd>стандартизация</kwd><kwd>ЯМР</kwd><kwd>масс-спектрометрия высокого разрешения</kwd><kwd>стандартные образцы</kwd><kwd>дейтериевая метка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>organophosphate pesticides</kwd><kwd>medicinal plant raw materials</kwd><kwd>standardisation</kwd><kwd>NMR</kwd><kwd>high-resolution mass spectrometry</kwd><kwd>reference standards</kwd><kwd>deuterium label</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was performed without external funding.</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">Reichert B, Pizzutti IR, Costabeber IH, Uclés A, Herrera S, Fernández-Alba AR.
