In this study we synthesized two closely related amphipathic peptides and show the mass directed flash purification of non-acetylated ‘18A’ from a crude mixture containing a single residue deletion sequence ‘17A’ (-Glu residue) using the Biotage® Isolera Dalton™.

Here we show how flash chromatography with mass directed fractionation can be used for purifying carbohydrate derivatives such as β-D-glucosamine pentaacetate 1 as a model compound, and other UV transparent or poorly UV absorbing compounds using either normal or reversed-phase chromatography.

Developed by collaboration with the University of Eindhoven, European Regional Marketing and R+D, this application note describes the application of Isolera Dalton to the detection of multiply charged peptide ions prior to purification. This effectively increases the range of the Isolera Dalton mass detection, for this class of compounds and demonstrates that Isolera Dalton is a fully integrated purification instrument rather than a simple MS based analytical tool.

Mass-directed flash purification is a simple and effective
technique to detect and fractionate compounds with poor UV chromophores. In this study, fatty acid methyl ester mixtures were purified by mass-directed flash purification using the Biotage Isolera™ Dalton System.

Natural product chemistry deals with discovering the previously unknown in nature. Compounds found in nature are typically found in low quantity and thus extractions are needed to isolate certain compounds classes or at least compounds with similar solubility.

Mephedrone (MCAT) is a ‘designer drug’ synthesised to mimic the amphetamine class of compounds. Due to its perceived ‘ecstasy like’ effects of euphoria, excitement and alertness combined with ease of availability, this (until recently) unregulated drug (legal high) has found widespread abuse in the UK in recent years. Harmful effects associated with mephedrone are still being studied but after several deaths were linked to the abuse of the drug, the UK Government made this a Class B substance. Mephedrone extraction was evaluated on three mixed mode cation exchange SPE sorbents: EVOLUTE® CX, EVOLUTE® WCX and ISOLUTE® HCX.
