(b), a sample of the compoundormixtureusedin a product’s formulation shall be tested utilizing one or both of the following methods for identification of LVP-VOC compoundsandmixtures:ASTM D2879 as modified in Appendix B of Method 310, and ASTM E1719, to determine if the compoundormixture...
Schiff bases are compounds of a great interest, as evidenced by the number of publications published annually on the topic within the last twenty years. Such a great interest can be explained by the fact that they are widely used in both organic and inorganic synthesis. The examples of organic...
Organic compoundsRational approach towards the QSAR/QSPR modeling requires the descriptors to be computationally efficient, yet physically and chemically meaningful. On the basis of existing simplex representation of molecular structure (SiRMS) the novel 'quasi-mixture' descriptors were developed in order ...
