We have successfully developed a rapid and efficient microwave-assisted protocol for the preparation of Neu5Ac congeners that are important intermediates for clinically-relevant derivatives of Neu5Ac. The syntheses were performed using readily available reagents, improved on established techniques, and used more benign reagent for peracetylation. Moreover, the protocol that we developed is 1 to 2 orders of magnitude faster than conventional methods.

For high efficiencyin parallel synthesisand method developement short reaction timesare essential. We have examinedthe possibilityof maintaining reported selectivitiesin rapid, high temperaturepalladium-catalyzed asymmetric allylic alkylations. Reactions were promotedby useof singlemode microwave heating(vide infra),which oppositeto conventional oilbath heating(wallheat transfer) rapidlyand almost homogeneouslyheat largeparts of the sample(internalheat transfer).

User report: RapidTrace. The Laboratory of Racing Chemistry (LRC) analyzes samples from racehorses for doping drug. In order to screen approximately 1000 samples per week, LRC use an array of Biotage RapidTrace automated SPE systems. In an interview, Mr. Kenji Kinoshita and Mr. Kensaku Shirai talked about their experiences with the RapidTrace system in processing the heavy workload.

Advanced bioanalytical techniques like LC/MS/MS and GC/MS are meeting the increasing demand for greater speed and specificity in toxicological screening. But conventional sample preparation methods have not kept pace. In particular, solid phase extraction (SPE), an essential step in the analysis of many biomolecules, has become a through-put limiting step in many laboratories.
The RapidTrace+ is a robust automated platform for quickly developing rugged, reliable SPE methods in regulated
pharmaceutical, clinical and forensic laboratories. The RapidTrace+ eliminates SPE bottlenecks so you can realize the
full benefits of today’s powerful analytical instruments.

Pure fractions are in high demand – impurities mean more work after purification. With new technology, fraction purity can be digitally analyzed directly during chromatography to reveal any problems on the fly. In this application we will show how the Isolera Spektra is used to determine fraction purity, eliminating the need for other post-purification analysis.

Our TurboVap II customers have been successful obtaining excellent recoveries for all semivolatile organic compounds (BNA, PAH, PCB, Pesticides, TPH/DRO, Herbicides). There are many factors that can impact the recoveries, such as client sample matrix, temperature, humidity, and extraction solvents. After gathering information from our customers, we have developed the guidelines below that will help your laboratory determine its optimum conditions for the TurboVap II.
