The formation of diarylethers by reacting an arylhalide and phenol is usually a reaction demanding long reaction times, high temperatures and strong bases, in order to obtain acceptable yield. The substitution patent of the electrophile and the nucleophile affects the reaction times mostly. A sterically hindered electrophile and a strongly deactivated nucleophile as outlined in the (Scheme 1) below, gives a very low yield (13 %) at conventional reflux for 2 weeks.1,2 Remainder was
recovered starting material. We have previously reported the dramatically shortened reaction time to 1 hour along with improved yield running the reaction outlined in the Scheme by heating by microwaves.

One of the most common flash purification challenges is
dealing with hard-to-dissolve crude samples. Because polar
solvents cause poor chromatographic results when used as
injection solvents in normal-phase flash chromatography, other

With the de-criminalization of recreational cannabis, containing the hallucinogen THC, and other cannabinoids with purported medicinal value, e.g. CBD (Figure 1), in several states a need for higher purity “products” has become a necessity. Current technology uses extraction with supercritical fluids or other non-supercritical solvents to remove the products of interest from other endogenous species such as lipids, terpenes, and chlorophylls as well as pesticides.
These techniques help clean up raw extracts and isolate cannabinoids with higher-purity but not to the levels desired by many producers so there is a developing need for a secondary purification step.

Endogenous phospholipids present in biological fluids are a major problem in LCMS/ MS analysis as they are often very difficult to remove during sample preparation. When phospholipids are not removed, they retain very strongly on reversed phase analytical columns. If high organic (end of run) washes are not incorporated into the LC methods these matrix components may elute in subsequent analyses causing regions of suppression/enhancement leading to inaccurate quantitation. This poster evaluates the use of polymer-based solid phase extraction (SPE) sorbents, incorporating hydrophobic and various mixedmode retention mechanisms to address the problems associated with phospholipid removal.

Endogenous phospholipids (outline structure shown in
Figure 1.) present in biological fluids are a major problem
in LC-MS/MS analysis. Due to their strong retention
characteristics in reversed phase chromatography
phospholipids tend not to elute as discrete peaks and are
often very difficult to separate from analytes of interest.
This co-elution often leads to areas of suppression or enhancement in the chromatogram which in turn can cause
quantitation issues. Supported liquid extraction (SLE) is an
analogous technique to traditional liquidliquid
extraction. This poster compares phospholipid removal using a wide variety of solvent combinations, pH control and polar extraction solvents on supported liquid extraction plates

In all areas of analytical laboratory testing it is vital to ensure proper quality measures are in place to reduce or eliminate cross contamination between samples, which could result in false positive and/or false negative results. In many cases sample carryover in the LC/MS system is checked early on in the method development process. However, one area that can often be overlooked the sample preparation stage. This involves all aspects including pipetting, sample transfer, extraction protocol, evaporation and mixing steps. This poster examines various stages of the sample preparation process to determine the potential for cross contamination and present approaches to minimize and or eliminate the effect. This is demonstrated via a series of dye experiments combined with analyte testing using LC-MS/MS.

For as long as column chromatography has been practiced by
organic and medicinal chemists there has been a concern that too
much methanol in the solvent system will dissolve the column’s
silica. This concern has come about because chemists often find a
solid white precipitate in collected fractions after purification. This
phenomenon is usually noticed when dichloromethane and
methanol are used as the mobile phase solvents.
In this poster we will show the results of a study that evaluated the
degree of dissolution for both granular and spherical silica in

Most drugs are excreted in urine as glucuronide conjugates. Hydrolysis using a beta-glucuronidase enzyme to convert the metabolites to their “free” form for analysis increases sensitivity. Red abalone (Kura Biotech), abalone (Campbell Scientific), and recombinant (IMCSzyme) beta-glucuronidase enzymes were evaluated to determine which provided the most complete hydrolysis of glucuronide metabolites without effecting the overall recovery of non-conjugated compounds.
