Application of C4H5NO2, 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., 105-34-0.

Nitrile is any organic compound with a −C≡N functional group. 105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate.The prefix cyano- is used interchangeably with the term nitrile in literature. Application of C4H5NO2.

Tabassum, Sumaiya;Sunaja Devi, K. R.;Govindaraju, Santhosh research published 《 Nano ZnO@PEG catalyzed one-pot green synthesis of pyrano[2,3-d]pyrimidines in ethanol via one-pot multicomponent approach》, the research content is summarized as follows. A facile one-pot multicomponent protocol for the synthesis of bio-active pyrano[2,3-d]pyrimidine derivatives by a one-step condensation reaction of substituted aldehyde, malononitrile/methyl cyanoacetate, barbituric acid has been demonstrated using nano ZnO@PEG as a catalyst at room temperature The present approach offers several advantages, such as shorter reaction time, higher yields, and environmentally friendly. Easy isolation of products, absence of column chromatog. purification, use of com. available low-cost starting materials and reusability of the catalyst make the methodol. viable in organic synthesis.
