Ethyl glucuronide (EtG) and ethyl sulphate (EtS) are specific metabolites formed within the body after the ingestion of alcohol. In forensic toxicology, when tested together they provide more specific evidence of alcohol intake. This application note demonstrates the simultaneous extraction of both EtG and EtS in the same assay and represents further optimization of AN718 which showed single EtG extraction without EtS. Recoveries for EtG range from 90-105% and 80-103% for EtS across two formats of EVOLUTE AX columns with RSDs <10%. The LOQ is 10 ng/mL for EtG and 2 ng/mL for EtS across both EVOLUTE AX formats.

The SNAP XL cartridges address a growing need for optimized gram- to ~100+ g-scale purification, increasing efficiency and reducing costs. These cartridges extend the
SNAP product ranges, providing chemists with more scalable tools for their synthesis and purification needs. There are 3 members in this family of cartridge solutions, KP-Sil for normal phase, C18 for reverse phase and KPNH for more difficult normal phase systems, such as amines. SNAP XL cartridges will allow you to save hours, even days of purification run-time.

New approaches to the quantitation of drugs and metabolites in biological fluids have increased the need for high throughput methodologies to avoid the traditional laboratory bottleneck of sample preparation. Solid phase extraction in a 96-well plate format such as ISOLUTE-96 Fixed Well Plates or ISOLUTE Array 96-well Plates is a solution to this problem.

Amide-linked homopolymers of sialic acid offer the advantages of stable secondary structure and increased bioavailability making them useful constructs for pharmaceutical design and drug delivery. Defining the structural characteristics that give rise to secondary structure in aqueous solution is challenging in homopolymeric material due to spectral overlap in NMR spectra. Having previously developed computational tools for heteroologomers with resolved spectra, we now report that application of these methods in combination with circular dichroism, NH/ND NMR exchange rates and nOe data has enabled the structural determination of a neutral, d-amide-linked homopolymer of a sialic acid analogue called Neu2en.

Biotage has created a new Resin-based Chemistry Kit that contains a variety of resins
designed to enable a choice of key resin-assisted chemistries with optimized protocols
(Figure 1). Reductive amination, coupling (C-C or C-O bond formation), amide bond
formation and oxidation are widely used traditional chemical transformations you’ll be able
to perform with this new kit.

Resins are usually described as one of 2 main types, Gel (PS) or macroporous (MP).
The gel resins have a low cross-linking and need to swell to allow access to their
functional groups. Therefore, they are very effective in transformations requiring
swelling organic aprotic solvents such as DCM, THF, Dioxane etc. Conversely, MP
resins are more highly cross-linked with more of a permanent open pore structure,
so they do not require swelling in such solvents for effective performance. As a
result, MP resins are compatible with a wider range of solvents than PS resins and
perform better in solvents such as water, MeOH and MeCN. Resins are generally
stable and can be stored indefinitely under cool dry conditions. For longer term
storage standard refrigeration (4 °C) is recommended.

Activated carbon is an adsorbent media used to remove colored compounds from solution. Using carbon in a packed bed, such as the Biotage FLASH-AC cartridge improves adsorbent performance. The key variable in optimizing the decolorization process is the solvent system. Varying the solvent system impacts the adsorbent capacity of the cartridge, affecting both the yield and purity of the product. Biotage FLASH-AC cartridges tolerate a wide range of process solvents. This note discusses solvent choice as a process variable and how it contributes to significant process improvement and reduces the total cost of operation.
