Chemistry is an experimental science, HPLC of Formula: C21H46BrN, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1120-02-1, Name is OctMAB
The DFT-based descriptors were used to derive the quantitative structure-activity relationship (QSAR) models enabling the calculated quantum chemistry parameters to be correlated to the toxicity of quaternary ammonium compounds (QACs) on green alga Chlorella vulgaris. DFT/B3LYP level of theory with the 6-31G(d) basis set was applied to calculate a set of quantum chemistry descriptors for 11 QACs. The partial least squares (PLS) analysis implemented in Simca-P was employed to obtain the QSAR models. The optimal PLS model with the cumulative cross-validated regression coefficient (Qcum2=0.893) and the correlation coefficient between observed values and fitted values (R=0.975) explained 95.3% of the variance of the independent variables and 92.8% of the variance of the dependent variable. The results of this investigation show that alkyl chain lengths (CL), polarizability tense (alphazz), the most positive net atomic charges on a hydrogen atom (qH+) and entropy (So) are the major descriptors in governing the log(1/EC50) values of the QACs.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C21H46BrN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1120-02-1, in my other articles.
