The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Wasfy, Ashraf Farouq, once mentioned the application of 103-36-6, Name is Ethyl cinnamate, molecular formula is C11H12O2, molecular weight is 176.21, MDL number is MFCD00009189, category is phthalazine. Now introduce a scientific discovery about this category, Application of 103-36-6.

Phthalazine derivatives attached to amino acid derivatives were synthesized with high yields. The reaction of phthalazine derivatives with different phthalyl and tosylamino acids such as glycine, alanine, phenylalanine, valine, serine, and threonine in the presence of N,N-dicyclo hexylcarbodiimide (DCC) as a dehydrating agent reagent yielded high yields of the afforded compounds. Phthalylamino acids derivatives were obtained by deprotection of phthalazine derivatives, with the latter heating with hydrazine hydrate. The chemical structures of all phthalazine derivatives were affirmed by elemental analysis and spectral data (IR, MS, (HNMR)-H-1, and C-13 NMR). Screening out and estimation of the synthesized derivatives for their cytotoxic and antioxidant activity were done, and most of them showed powerful activity in comparison with standard drugs.

Application of 103-36-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 103-36-6 is helpful to your research.

An eco-friendly and efficient green protocol is developed for the synthesis of sixteen pyrazolo-phthalazine derivatives (5a-p) by using inexpensive biodegradable eggshell powder (ESP) as a heterogeneous catalyst. The four-component one-pot condensation reaction proceeded through Knoevenagel-Michael reaction of different chosen active methylene compounds, phthalic anhydride, and hydrazine hydride with various substituted aromatic aldehydes in the water at 60 degrees C, and furnished the high yields of products (93-98%) in rapid reaction time of 28 to 45 min. The material was characterized by different analytical techniques (SEM, TEM, XRD, BET, and FT-IR), and was composed of the high percentage of calcium oxides and carbonates, and less percentage of Na and Mg elements (based on EDX analysis). The ESP material displayed recyclability (4 times) without any notable loss of catalytic efficacy.

The understanding and control of proton transfer reactions between acid-base pairs in the solid state are two of the main challenges for the crystal engineering community. The ability to control proton transfer reactions in the solid state enables a more selective preparation of cocrystals and salts, which facilitates the design of solid materials with specific physicochemical properties. In this study, an approach to control proton transfer reactions of an E-butenedioic acid/phthalazine cocrystal-salt (hybrid) system is presented, which allows the selective formation of its cocrystal and salt. In this approach the dominant intermolecular interactions between acid-base pairs are identified. Such interactions appear to be crucial for the inhibition or promotion of proton transfers in the solid state. For this, the relationship between these interactions and the so-called ApKa rule has been investigated.

The reactions of [Ru-3(CO)(12)] with four aromatic diazines have been studied in THF at reflux temperature. With phthalazine (L-1), the compound [Ru-3(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(7)] (1), which contains an intact phthalazine ligand in an axial position bridging an Ru-Ru edge through both N atoms, is initially formed but it reacts with more phthalazine to give [Ru-3(kappa N-2-L-1)(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(6)] (2), in which a pi-pi stacking interaction between the aromatic rings of both ligands determines their position in cluster axial sites on the same face of the Ru3 triangle. With quinazoline (HL2), the cyclometalated hydrido decacarbonyl derivative [Ru-3(mu-H)(mu-kappa(NC4)-N-2-C-3-L-2)(CO)(10)] (3) is initially produced but it partially decarbonylates under the reaction conditions to give [Ru-6(mu-H)(2)(mu-kappa(NC4)-N-2-C-3-L-2)(mu(3)-kappa(3)-(NNC4)-N-1-C-3-L-2)(CO)(19)] (4), which results from the displacement of a CO ligand of 3 by the uncoordinated N-1 atom of another molecule of 3. With 4,7-phenanthroline (H2L3), the stepwise formation of the cyclometalated derivatives [Ru-3(mu-H)(mu-kappa(NC3)-N-2-C-4-HL3)(CO)(10)] (5) and two isomers of [Ru-6(mu-H)(2)(mu(4)-kappa(NCNC8)-N-4-C-4-N-3-C-7-L-3)(CO)(20)] (6a, 6b) takes place. In compounds 6a and 6b, two Ru-3(mu-H)(CO)(10) trinuclear units are symmetrically (C-2 in 6a or C-S in 6b) bridged by a doubly-cyclometalated 4,7-phenanthroline ligand. With 2,3′-bipyridine (HL4), two products have been isolated, [Ru-3(mu-H)(mu-kappa N-2(3)’ C-4′-L-4)(CO)(10)] (7) and [Ru-3(mu-H)-(mu-kappa(NN3)-N-3-N-2’C-2′-L-4)(CO)(9)] (8). While compound 7 contains an N-3′ C-4′-cyclometalated 2,3′-bipyridine, in compound 8 an N-3′ C-2′-cyclometalation is accompanied by the coordination of the N-2 atom of the remaining pyridine fragment. The structures of compounds 2, 3, 4, 6a and 8 have been determined by X-ray diffraction crystallography.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 5267-64-1, Name is D-Penylalaninol, molecular formula is , belongs to phthalazine compound. In a document, author is Aguilo, Joan, Quality Control of D-Penylalaninol.

Much attention has been paid to heterocyclic N-containing ligands due to their applicability as bridging ligands in the synthesis of redox active dinuclear metal complexes. With this aim, we report the synthesis and full characterization of a novel phthalazine-triazole ligand (1,4-bis(1-methyl-1H-1,2,3-triazol-4-yl) phthalazine). Moreover, we show that the phthalazine nitrogen atoms of this N-heterocyclic ligand are more reactive towards alkylating agents than the triazole groups. New ruthenium(II) complexes containing this ligand have been obtained and characterized both structurally and electrochemically. The geometry imposed by the ligand allows the placement of two ruthenium centers in very close proximity so that efficient through-space interactions take place, a concept of crucial importance for electron transfer processes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5267-64-1 is helpful to your research. Quality Control of D-Penylalaninol.
