Chromatography aims to separate an analyte mixture into sharp, symmetrical, and well-resolved peaks for quantitative and qualitative analysis. To do this, it is crucial to understand ionization and the ionic form(s) of analytes at a given pH. The use of predictive software tools allows quick selection of optimal conditions and helps build robustness into methods from the start.

Most of us who’ve worked in chemistry know about logP. The partition coefficient makes it into Lipinski’s rule of five and most post-secondary educations. But when it comes to logP, we mean one exact chemical structure. If a compound ionizes, it’s not the same structure. And since most compounds investigated in pharmaceutical and pharmacological research contain ionizable sites, it’s not logP we should be concerned about, but logD.

As corporate distributed environments are becoming the norm, there is a need for a multi-user, multi-location online lab environment as well. To that end, ACD/Labs has added a new deployment option on our Percepta Platform that allows end users to access our property calculators remotely from any location at any time—Percepta Portal.
