Abstract:As a typical meta-Diamide (m-diamide) insecticide, Broflanilide is highly effective, exhibits low toxicity, and shows no cross resistance with traditional insecticides that act on the γ-aminobutyric acid (GABA) receptor. As a high halogen content potentially causes risks and was concerning to researchers, easily derivatized
Abstract:This paper shows that Mendeleyev's 2D periodic table of elements cannot accommodate 2787 isotopic elements. Only by constructing a "three-dimensional periodic law" can cover all the isotopic elements.
Abstract:To explore the challenges faced by chiral drug preparation techniques and propose corresponding solutions, We introduce the background and significance of chiral drug preparation technology, Subsequently, we analyze in detail various challenges faced in the current preparation of chiral drugs, including selectivity in asymm
Abstract:The research and application of chiral drugs has attracted increasing attention, to explore the development trends of chiral drug synthesis technology,this paper introduce related green chemistry and emerging technologies, elaborates on the application of green chemistry in chiral drug synthesis, including catalyst design a
Abstract:The paper considers the possibility of using aqueous extracts of conifers to increase the germination of seeds of Scots pine for long-term storage. It was found out that in the woody greens of conifers there are substances with provitamin and growth-stimulating activity, namely carotenoids (0.14 g/l) and phenolic compounds
Abstract:The DENV dengue virus belongs to the Flaviviridae family, a group of four serotypes that circulate freely in the different endemic regions causing dengue disease. This disease is transmitted by the female Aedes aegypti and Aedes albopictus mosquitoes. Due to the variety of serotypes and genotypes existing in the same zone,

Abstract:The mixtures of two hydroxylic components (alcohols and phenols) reacted with CH2Cl2 in basic medium under the conditions of the solid-liquid phase-transfer catalysis to furnish the mixtures of three possible formaldehyde acetals separable under ordinary column chromatography. Using 7 phenols and 7 alc
Abstract:NaNO2 crystal is biaxial, achiral and ferroelectric ionic solid at room temperature. It belongs to the symmetry class mm2. The magnitude and sense of optical rotation with opposite signs are determined in the two optic axis directions, OA1 and OA2, of the crystal model at four wavelengths. The handedness of the c
Abstract:Effectiveness of passivation of large PbSe colloidal quantum dots (CQD) (first excitonic peak position 2 - 2.8 μm) using commonly used passivants is studied. The kinetics of oxidation over a period of up to more than one year is investigated. The effect of in-situ passivation with CdCl2, NH4Cl, Tetrabutylammonium Iodide (TB
Abstract:Process related two impurities of Dapsone were synthesized by applying cu-catalyzed conversions for the impurity profile and toxicological study. Controlled mono-diazotization of Dapsone followed by insitu iodination is the key step of our synthesis.
