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. Safety of Methyl 2-cyanoacetate.
Lebrun, Stewart;Chavez, Sara;Chan, Roxanne;Nguyen, Linda;Jester, James V. research published 《 Ascorbic acid specifically reduces the misclassification of nonirritating reactive chemicals in the OptiSafe macromolecular eye irritation test》, the research content is summarized as follows. Recently, we showed that the addition of physiol. concentrations of ascorbic acid, a tear antioxidant, to the OptiSafe macromol. eye irritation test reduced the false-pos. (FP) rate for chems. that had reactive chemistries, leading to the formation of reactive oxygen species (ROS) and mol. crosslinking. The purpose of the current study was to 1) increase the number of chems. tested to comprehensibly determine whether the antioxidant-associated reduction in OD is specific to FP chems. associated with ROS chemistries and 2) determine whether the addition of antioxidants interferes with the detection of true pos. (TP) and true neg. (TN) ocular irritants. We report that when ascorbic acid is added to the test reagents, retesting of FP chems. with reactive chemistries show significantly reduced OD values (P < 0.05). Importantly, ascorbic acid had no significant effect on the OD values of TP or TN chems. regardless of chem. reactivity. These findings suggest that supplementation of ascorbic acid in alternative ocular irritation tests may help improve the detection of TN for those commonly misclassified reactive chems.
Safety of Methyl 2-cyanoacetate, 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.
