Thin-layer chromatography (TLC) is a commonly used method development tool for flash purification. Product mixtures separated using TLC generally can be purified by flash chromatography using the identical solvent system. The method transfer accuracy of TLC to flash is based on the TLC silica and flash silica properties. When identical, the equation 1/Rf = CV holds, where Rf is the retention factor of a compound separated by TLC, and CV is the number of column volumes required to elute a compound. Cartridge loading capacity is based on the difference in CV (DCV) between two adjacent compounds.

The utilization of bound reagents for the solution phase synthesis has become an important tool in synthesis of biologically active molecules. The disadvantage of this technique is the relative slow rate of reaction. Microwave irradiation has been used to overcome this problem and increase rate of reaction of solid-assisted solution phase synthesis. This presentation covers developing efficient and robust strategies for the preparation of an array of cyclic tertiary amines using microwave irradiation in conjunction with bound reagents and scavengers such as MP-cyanoborohydride.

The crossreactivity of molecularly imprinted polymers (MIPs) and its
practical implications are discussed. Screening of MIP libraries is presented as a
fasttrack route to discovery of resins selective towards new targets, exploiting the
fact that MIPs imprinted with one type of template molecule also show recognition
to related and sometimes also to apparently unrelated molecules. Several examples
from our own and others’ studies are presented that illustrate this crossreactivity and
the pattern of recognition is discussed for selected examples.

The US EPA monitors a variety of chemicals in water that may cause harm to humans or wildlife to minimize exposure. Method 625 was developed by the Office of Science and Technology in the Clean Water program to monitor a large suite of semivolatile chemicals in wastewater for compliance with the National Pollution Discharge Elimination System (NPDES).

Safety is always a prime consideration in a laboratory. While working with organic solvents and samples that may contain harmful analytes, it makes sense to shield the operator from hazardous conditions whenever possible.

Traditional approaches to compound purification involving chromatography utilize large volumes of relatively toxic and expensive solvents, and significantly contribute to the environmental footprint of organizations involved in molecular research. Current directives for greener chemistry have put pressure on organizations to reduce the
environmental impact of their work.

Bei herkömmlichen Aufreinigungsverfahren mittels Chromatographie kommen große Mengen verhältnismäßig giftiger und teurer Lösungsmittel zum Einsatz, die sich negativ auf den ökologischen Fußabdruck von Unternehmen in der Molekularforschung auswirken. Neue Richtlinien für einen verantwortungsvolleren Umgang mit Chemikalien zwingen Unternehmen, die Umweltauswirkungen ihrer Arbeit zu reduzieren. Durch Einblicke in die Arbeitsabläufe dieser Unternehmen und neue Entwicklungen im Bereich Flash-Chromatographiesysteme und -säulen lassen sich Verbrauch und Toxizität der für die Aufreinigung eingesetzten Lösungsmittel und somit auch die Umweltbelastungen dieser Verfahren reduzieren.
