ISOLUTE® Si-Propylsulfonic acid (SCX-2) belongs to a class of strong supported acids. As a bound sulfonic acid, it has a natural propensity to bind alkali and some transition metal group metals, which means that it can be used as a scavenger for metals with a +I or +II oxidation state, such as Na, K, Li, also
Pd, Rh, and Ru.

ISOLUTE® Si-Propylsulfonic acid (SCX-2) belongs to the class of strong acids. Similar
to ISOLUTE Si-TsOH (SCX-3)1, it can be used to (a) scavenge amines and other bases such
as anilines and borohydrides (b) as an acid catalyst in reactions or (c) as a replacement
for aqueous or organic acids in quenching reactions. The advantage of using SCX-2 as a
bound acid reagent is in that it eliminates work-up. The crude reaction mixture can be evaporated to dryness and the resulting free flowing solid can be purified directly by flash column chromatography.

The ability to synthesize peptides in a range of different
scales is a requirement in many research laboratories. The
Biotage® Initiator+ Alstra™ fully automated microwave peptide
synthesizer has a scale range of 5 μmol up to 2 mmol using
three different reactor vial sizes (5 mL, 10 mL and 30 mL).
The acyl carrier protein fragment, ACP (65–74), H-Val-Gln-
Ala-Ala-Ile-Asp-Tyr-Ile-Asn-Gly-NH2 (VQAAIDYING-NH2) (1), is
a well-known so-called difficult sequence and is commonly
used to evaluate the performance of new synthesis reagents
Here we demonstrate a variable scale synthesis on the
Initiator+ Alstra using the ACP (65–74) fragment as a model

This application note describes the use of ISOLUTE® HM-N as a support material
for pre-adsorption of a reaction mixture prior to flash chromatography. This
approach is useful when loading reaction mixtures that are only soluble in polar
solvents onto a Biotage® SNAP Ultra, SNAP KP-SIL or SNAP KP-NH column.

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.

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.

Biotage metal scavengers are a more effective alternative to traditional carbon batch adsorption processes. They have the lowest metals content, and also excellent extractable profiles, therefore not likely to risk contamination, unlike competitive materials we tested. Furthermore, Biotage metal scavengers offer volumetrically, a much more compact solution than carbon, requiring 48 times less volume for the same degree of Pd removal in our studies.
