Related Products of 125-20-2, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 125-20-2, Name is Thymolphthalein,introducing its new discovery.

The solubilization effect of 14-s-14 series dicationic surfactants is quantified via spectrophotometry using a thymolphthalein hydrophobic indicator. It is shown that the solubilization capacity of the studied micellar solutions with respect to the neutral form of thymolphthalein increases along with the length of the spacer moiety and grows by as much as five times upon transitioning from 14-2-14 to 14-6-14. It is concluded that the solubilization of thymolphthalein is accompanied by a shift in the acid-base equilibria in which this compound participates, as is reflected in the drop of its pK a value and the shift of the region of color change.

The description relates to imide-based compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

Uncialamycin analogs were evaluated as potential cytotoxic agents in an antibody-drug conjugate (ADC) approach to treating human cancer. These analogs were synthesized using Hauser annulations of substituted phthalides as a key step. A highly potent uncialamycin analog 3c with a valine-citrulline dipeptide linker was conjugated to an anti-mesothelin monoclonal antibody (mAb) through lysines to generate a meso-13 conjugate. This conjugate demonstrated subnanomolar potency (IC50 = 0.88 nM, H226 cell line) in in vitro cytotoxicity experiments with good immunological specificity to mesothelin-positive lung cancer cell lines. The potency and mechanism of action of this uncialamycin class of enediyne antitumor antibiotics make them attractive payloads in ADC-based cancer therapy.

The direct coupling of various aldehydes and ketones with CH2Br2 or CH2Cl2 promoted by TiCl4-Mg bimetallic complex provides an extremely simple, practical, and efficient approach for the construction of bromomethyl or chloromethyl carbinols. The high chemoselectivity of this chemistry is illus-trated by the TiCl4-Mg-promoted selective coupling of CH2Br2 or CH2Cl2 with an aldehyde in the presence of ketone and selective transfer of CH2Br or CH2Cl to saturated carbonyl moiety. This protocol is also suitable for sterically hindered and enoliza-ble carbonyl compounds.

Thermochromic films with intriguing functionalities have great potential in soft actuators, heat storage devices, and interactive interface sensors. Inspired by the unique features of bird feathers (such as Nicobar pigeon, Anna hummingbird, mandarin duck, etc.), a superhydrophobic thermochromic film (STF) with robust healability is proposed for the first time through sandwiching an electric heater between a top thermochromic layer and a bottom poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) substrate. The STF exhibits fast and reversible color conversions of blue-pink-yellow under a low input power and has a superhydrophobic property with a contact angle of 155. Furthermore, owing to the strong dynamic dipole-dipole interactions between the polar CF3 groups of flexible PVDF-HFP chains, the STF possesses a robust healing capability of structure and conductivity. By means of the temperature difference generated by the objects contacting (finger, iron, and water) as a stimulus, the STFs achieve tactile imaging and writing record with advantages of transient display, automatic erasure, and excellent reusability. Additionally, the STF-based anti-counterfeiting security labels with superhydrophobicity and three-state color switching simultaneously realize facile distinguishment and difficult forgery. The findings conceivably stand out as a new methodology to fabricate functional thermochromic materials for innovative applications.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1552-42-7, help many people in the next few years.Application In Synthesis of Crystal violet lactone

Reference of 1563-38-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1563-38-8, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, introducing its new discovery.

A luxAB-mutant of the carbofuran degrading bacterium Burkholderia cepacia PCL3 was successfully constructed with the capability to emit a luminescence signal of 1.6×10-3RLUcfu-1. The mutant has a growth pattern and carbofuran degradation ability similar to PCL3 wild-type. The luminescent emission by PCL3:luxAB1 directly correlated with the metabolic activity of the cells. The optimal pH, temperature and n-decanal concentration for luminescence emission are 7.0, 35C and 0.01%, respectively. PCL3:luxAB1 was used to assess the toxicity of carbofuran and carbofuran phenol in basal salt medium (BSM) in which the different sensitivity of the cells is dependent on the biomass concentration. With the luciferase system, the degradative fraction of the augmented PCL3:luxAB1 and the difference between the active augmented PCL3:luxAB1 and indigenous microorganisms at the contaminated site could be indicated.

A series of addition-type imide oligomer (degree of polymerization: n=1-9) derived from 2,3,3′,4′-diphenyl ether tetracarboxylic acid dianhydride (a-ODPA), 3,4′-oxydianiline (3,4′-ODA) and 4-phenylethynylphthalic anhydride (PEPA) was synthesized by thermal imidization. The resultant oligomers were characterized for their chemical architecture, thermal property, and processability. The experimental results showed that oligomers PI-1 and PI-2 had somewhat crystalline phase. PI-4, PI-6 and PI-9 exihibited high solubility in solvents. These imide oligomers have a very low melt viscosity, and thus provide wide processing window by the rheological behaviors. Furthermore, the cured polyimides exhibited excellent thermal stability under N2 atmosphere. The temperatures of 5? weight loss in N2 atmosphere were all above 524C.
