Predicting the acute toxicity of a large dataset of diverse chems. against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approx. ratio of 1 : 1. Only six mol. descriptors were used to establish the quant. structure-activity/toxicity relationship (QSAR/QSTR) model for 96 h pLC50 through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R2 = 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (qint2 = 0.699 and qext2 = 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six mol. descriptors and a large data set for the test set consisting of 481 compounds This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Product Details of 763-69-9).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Product Details of 763-69-9
