This work proposes OCLAS (Organic Chemistry Language Ambiguity Solver), an automatic system to analyze syntactically and semantically Organic Chemistry compound names and to generate the pictures of their chemical structures. If both parses detect that the input name corresponds to a theoretically possible organic chemical compound, the system generates its molecular structure picture, whether ...

Three selected phenothiazines and their demethylated derivatives are chromatographed on different C18 bonded reversed-phase liquid chromatography columns. A quadratic equation fits the relationship log k versus the organic modifier percentage. When acetonitrile is the organic modifier, the demethylated derivative is eluted before the parent compound, whereas it is eluted after when methanol is ...
