Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Product Details of C4H5NO2.
Wang, Taisheng;Shen, Lei;Wang, Haoxiang;Zhang, Na research published 《 A highly selective fluorescent sensor for ratiometric detection of cyanide in aqueous solution and solid states》, the research content is summarized as follows. Designing fluorescent sensors for selective detection of CN– in aqueous and even solid states are still rarely reported due to the aggregation-caused quenching (ACQ) effect. In this paper, we report a novel fluorescent probe C-1. Due to the AIE effect, C-1 displayed obvious orange-red fluorescence with emission peak centered at 597nm in aqueous solution and solid state. Under the influence of electron withdrawing cyano and ester groups, the vinyl C=C bond was easy to be attacked by nucleophilic CN–, which destroyed the conjugated bridge and also blocked the ICT process between the donor and the acceptor. The emission band shifted from 597 nm to 475 nm consequently. Other anions have no effect on the fluorescence of C-1. Thus, C-1 could be used as a selective CN– sensor. The UV-visible and fluorescent measurement confirmed the interactions between C-1 and CN–. 1H NMR titration method further demonstrated the detection mechanism. The sensitivity and detection limit of C-1 were measured to be 5.97 x 104 M-1 and 1.2 μM resp. Due to the solid-state emission nature, C-1 immersed test strip was prepared and used as an effective test kit to detect CN ion.
105-34-0, Methyl cyanoacetate is an alkyl cyanoacetate ester.
Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Knövenagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α -cyanocinnamic esters.
Methyl Cyanoacetate is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate (M287290); a compound used in the synthesis of DPP-IV inhibitors for treating type 2 diabetes., Product Details of C4H5NO2
