ISOLUTE® 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. Since SCX-2 is acidic in nature, it is typically used as a metal scavenger when the target product is not basic, to avoid the obvious acid/base product binding interactions with the scavenger.

This study was conducted in 3 parts.
Metal scavengers were investigated for inherent metals content by ICP analysis methods.
Additionally these scavengers were extracted in a range of common solvents in order to show extractable/leachable levels.
We demonstrate an example metal scavenging mitigation step, looking at the corresponding API mass yield, purity and also metals data.

Biotage are leaders in metal scavenging in a variety of different
application areas.
Tags: Manuals & User Guides
Utilization of synthetic chemistry routes developed in late lead
optimization is becoming more widespread as the desire to
efficiently confirm pre-clinical compounds has increased. In some
cases, chemical processes use reagents which are specific and
cannot be substituted on scale up. Such reagents include transition
metal catalysts.

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.

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. SCX-2 is typically used as a metal scavenger when the target product is not basic, to avoid the obvious acid/ base product binding interactions with the scavenger. If the product is basic then Si-Tiol, SI TMT, MP-TMT or Si-Trisamine may be utilized instead. Other uses in chemistry include (a) scavenge (removing) amines and other bases from solution (b) as an acid catalyst in reactions or (c) catch and release purification of amines, to facilitate either solvent switching or amine purification. The advantage of using SCX-2 as a polymer supported acid is that it eliminates traditional laborious work-up steps.
