497-25-6, Name is Oxazolidin-2-one, belongs to oxazolidine compound, is a common compound. Electric Literature of 497-25-6In an article, once mentioned the new application about 497-25-6.

Antibiotics existing in wastewaters must be degraded to eliminate its antibacterial activity before discharging into the environment. Electrochemical reduction by continuous electrons supply can degrade various refractory pollutants, however, the information about the feasibility and characterization of the cathodic degradation of nitrofurans antibiotic furazolidone (FZD) is scarce. Here, we investigated the degradation of FZD using a poised cathode electrochemical reactor. The cyclic voltammetry (CV) preliminarily proved the feasibility of FZD degradation on cathode. In contrast to the different buffer solutions concentrations, buffer types, and initial FZD concentrations which only had obvious impact on the FZD degradation efficiency, different cathode potentials had significant effects both on the FZD degradation efficiency and degradation products composition. Catholyte PBS could be replaced by Na2CO3-NaHCO3 and NaCl buffer solution for the FZD degradation. The cathodic degradation pathway of FZD was proposed based on intermediate products analysis. When the cathode potential was lower than -0.75V, both the furan ring and oxazole ring of FZD were destroyed to generate linear chain products after N-N bond disconnection, suggesting that the high toxic biological metabolite of FZD, 3-amino-2-oxazolidinone (AOZ) could be detoxified by cathodic degradation. This study suggests that the electrochemical reduction could serve as a potential strategy for the treatment of FZD and AOZ containing wastewater.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Quality Control of Oxazolidin-2-one

1H NMR spectroscopic methods have been applied to compare the in vitro reactivity of the renal papillary nephrotoxin 2-bromoethanamine (BEA) with those of selected halide-substituted nephrotoxic analogues, 2-chloroethanamine (CEA), 2-fluoroethanamine (FEA), and 1-phenyl-2-iodoethanamine (PIEA). The primary 1H NMR-detectable transformation during a 24 h incubation of confluent Madin Darby canine kidney (MDCK) cells with BEA, CEA, and FEA (at concentrations up to the IC50 determined by neutral red uptake) was the appearance in cell culture media of 2-oxazolidone (OX). Additional novel signals assigned as FEA carbamate (N-carbanoyl-2-fluoroethanamine) were observed in media collected following incubation of cells with FEA. We propose that N-carbamate intermediates are formed from the spontaneous reaction of these haloalkylamines with HCO3–buffered growth media and that OX is formed from the carbamate via elimination of the hydrogen halide. Further 1H NMR experiments, conducted for up to 8 h at 25 deg C on 5 mM solutions of BEA, CEA, and FEA in (2)H2O containing a 20-fold excess of HCO3- at pH 7.6, demonstrated a time-dependent decrease in the concentration of the free haloalkylamines accompanied by the production of N-carbamate intermediates and OX. Under these pseudo-first-order reaction conditions, the formation of OX from BEA was complete within approximately 6 h. In similar reaction conditions OX formation from CEA (24 h after initiation) had reached 54 percent of its final equilibrium concentration. Equivalent experiments demonstrated that PIEA was almost completely converted to 4-phenyl-2-oxazolidinone (PHOX) within 2 h. These observations reveal the strong disposition of this series of haloalkylamines toward reaction with HCO3- and indicate that the compounds in this family may exist only transiently as free amines in vivo, where there will virtually always be excess HCO3-. The physiological relevance of the in vitro findings is further indicated by the NMR-detectable conversion of BEA to OX and also an alkylating aziridine (AZ) moiety in rat plasma containing BEA. The ability to form carbamoylated species and OX (or PHOX) may mediate the toxicity of this series of haloalkylamines and hence is potentially of considerable significance.

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.Quality Control of Oxazolidin-2-one, you can also check out more blogs about497-25-6

A new amphiphilic biodegradable beta-cyclodextrin/poly(l-leucine) (beta-CD-PLLA) copolymer was synthesized by ring-opening polymerization of N-carboxy-l-alanine anhydride (LL-NCA) in N,N-dimethylformamide (DMF) initiated by mono-6-amino-beta-cyclodextrin (H2N-beta-CD). The structures of the copolymers were determined by IR, 1H NMR and GPC. The fluorescence technique was used to determine the critical micelle concentrations (CMC) of copolymer micelle solution. The diameter and distribution of micelles were characterized by dynamic light scattering (DLS) and its shape was observed by transmission electron microscopy (TEM). The results showed that LL-NCA could be initiated by H2N-beta-CD to produce the copolymer. These copolymers could self-assemble into nano-micelles in water. The CMC of copolymer solution and the size of micelle reduced with increasing proportion of the hydrophobic part. TEM images demonstrated the micelles are all spherical. Such block copolymers could be expected to find applications in drug delivery systems and other biomedical fields.

In a Conference Paper，once mentioned of 497-25-6

Binary room-temperature complex electrolytes have been synthesized based on lithium perchlorate (LiClO4) and organic molecules with acylamino groups, including acetamide, ethyleneurea, 2-oxazolidinone (OZO), urea, methylurea (NMU) and 1,3-dimethylurea (DMU). Both LiClO4 and all organic molecules with acylamino groups are solid at room-temperature, but their mixtures at the proper molar ratio are liquid with a liquidus temperature about below 25C characterized by differential scanning calorimetry (DSC). Infrared spectroscopic studies show that the organic molecules can coordinate with the Li+ cation and the ClO4- anion via their polar groups (the C=O and NH groups). Such strong interactions lead to the dissociation of LiClO4 and the breakage of the hydrogen bonds among the organic molecules, resulting in the formation of the complex systems. Electrochemical performances of the complex electrolytes are evaluated with ac impedance spectroscopy, cyclic voltammetry (CV), and in a test electric double layer capacitor (EDLC), respectively. The LiClO4-acetamide electrolyte at molar ratio 1:5.5 exhibits the highest ionic conductivity, 1.25×10-3 Scm-1 at 25C and 11.5×10 -3 Scm-1 at 80C. The analysis for the CV behavior indicates that the electrochemical stability windowof these electrolytes is above 3V. The results demonstrate that these complex systems are promising electrolyte candidates for supercapacitor and probably other electrochemical devices.

[Chemical Equation Presented] Pamamycin 621A was synthesized through a convergent route, with the THF rings constructed from Evans aldols in the presence of the chiral auxiliaries without suffering racemization or elimination. The basic amino group was introduced at a late stage through reduction of an azido group with n-Bu3SnH, which also demonstrates for the first time the great potential of this largely forgotten reduction protocol in synthesis of multifunctional substrates.
