A series of N-alkylphthalazinone were synthesized by the reaction of phthalazin-1(2H)-one derivatives 1a-c with alkylating agents namely, propargyl, allyl bromide, epichlorohydrin, 1,3-dichloro-2-propanol, 4-bromobutylacetate, and 1-(bromomethoxy) ethyl acetate to give the corresponding N-alkylphthalazinone 2a-c, 3a-c, 5a-c, 6a-c, 7a-c, and 9a-c. Alkylation of phthalazin-1(2H)-thione to give a series from S-alkylphthalazine 12-14 and thioglycosides 15 and 17 was performed. Deprotection of compounds 7a-c, 9a-c, 15, and 17 resulted in the formation of the corresponding products 8a-c, 10a-c, 16, and 18. The structure of newly synthesized compounds was assigned by IR, H-1, C-13 NMR, and elemental analysis. Some of these compounds were screened for antiviral and antimicrobial activity.

In this, we performed a four component domino reaction of phthaloyl dichloride, hydrazine hydrate, indole-3-carboxaldehydes and malononitrile/ethyl cyanoacetate to form 1-(1H-indol-2-yl)-1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by in situ generation of HCl as catalyst in refluxing ethanol for 1 h in good yields. This four component domino reaction transformation presumably proceeds via addition/dehydrohalogenation/condensation/cyclization of reactions. The material was thoroughly characterized at various stages of its formation by means of FTIR, NMR spectroscopic and Mass spectrometric analysis and is confirmed to be the derivative of 1-(1H-indo1-2-yl)-1H-pyrazolo [1,2-b]phthalazine-5,10-dione.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 23981-47-7. SDS of cas: 23981-47-7.

A convenient, environmentally friendly and efficient procedure for the synthesis 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H,13H)-trione derivatives has been developed via multi-component and one-pot reactions of various aldehydes with cyclic 1,3-diketones and phthalhydrazide 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). In simple and mild reaction conditions, the use of HFIP is explored as an easy workup and a green catalyst for the one-pot three-component synthesis of 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H, 13H)-triones. Thus, this practical method is developed as a notable medium for these derivatives via a multicomponent reaction.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 81-16-3. Safety of 2-Aminonaphthalene-1-sulfonic acid.

A probe mediated SERS-based strategy is developed to selectively detect hydrazine with superb sensitivity. Ortho-phthaldialdehyde, a simple probe, reacts specifically with hydrazine to form phthalazine, a molecule that possesses a larger Raman cross section and better affinity toward the SERS substrate. We observed a limit of detection of 8.5 X 10(-11) M. Our method shows both qualitative and quantitative measurement of hydrazine with high sensitivity, low cost, and fast analysis time.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 502496-34-6. Name: 4-Bromo-2-fluoro-6-nitrotoluene.

Phosphoric acid-doped sulfonated poly(tetra phenyl phthalazine ether sulfone) (PA-SPTPPES) copolymers were successfully synthesized by the 4,4′-dihydroxydiphenylsulfone with 1,2-bis(4-fluorobenzoyl)-3,4,5,6-tetraphenylbenzene (BFBTPB) and 4,4′-difluorodiphenylsulfone in sulfolane. Poly(tetra phenyl phthalazine ether sulfone)s (PTPPESs) were prepared via an intramolecular ring-closure reaction of dibenzoylbenzene of precursor and hydrazine. The sulfonated poly(tetra phenyl phthalazine ether sulfone) (SPTPPES) membranes were obtained by sulfonation under concentrated sulfuric acid, and followed phosphoric acid-doped by immersion in phosphoric acid. Different contents of doped and sulfonated unit of PA-SPTPPES (10, 15, 20 mol% of BFBTPB) were studied by FT-IR, H-1 NMR spectroscopy, and thermo gravimetric analysis (TGA). The ion exchange capacity (IEC) and proton conductivity of SPTPPESs and PA-SPTPPESs were evaluated with increase of degree of sulfonation and doping level. The PA-SPTPPESs membranes exhibit proton conductivities (80 degrees C, relative humidity 30%) of 41.3 similar to 74.1 mS/cm and the maximum power densities of PA-SPTPPES 10, 15, and 20 were about 294, 350, and 403 mW/cm(2).

Healthcare careers for chemists are once again largely based in laboratories, Related Products of 1676-73-9, although increasingly there is opportunity to work at the point of care, helping with patient investigation. 1676-73-9, Name is H-Glu(OBzl)-OH, SMILES is N[C@@H](CCC(OCC1=CC=CC=C1)=O)C(O)=O, belongs to phthalazine compound. In a document, author is Yun, Yanbin, introduce the new discover.

This paper reports an evaluation of the effect of both organic and inorganic additives on the gelation kinetics, morphology and separation properties of asymmetric poly(phthalazine ether ketone) (PPEK) hollow fiber ultrafiltration membranes. Using an online optical microscope-CCD camera for observation of precipitation front movement (X), a good linear relationship between X-2 and time was observed for the whole gelation process with the correlation coefficient (R-2) higher than 0.98. It was found that the pure water flux of membranes with additives were lower than neat PPEK membranes. This observation might be attributed to the decrease in the face gelation velocity caused by the extra organic additives. The water flux of PEG600 was higher than that of Tween80 at the same additive concentration. When OA concentration increased from 3.5 to 5.0 wt.%, the pure water flux increased from 332 to 367 L/m(2) hand the rejection decreased from 98.6 to 96.8%. The PPEK hollow fiber membranes exhibited finger-like macrovoids structure and a skin layer at the outer-most region of the hollow fiber. Evaluation of the membrane chemical resistance with various chemical solutions indicated that PPEK membranes had good chemical resistance against HCI, H2SO4, HNO3, CH3COOH, OA, NaOH and H2O2, while the NaClO solution can greatly damage the membrane mechanical strength. Static sorption tests of PPEK membrane revealed that PPEK membrane adsorbed more bacitracin than BSA due to the smaller size of bacitracin. (C) 2011 Elsevier B.V. All rights reserved.
