Non-polar SPE is commonly used for extraction of acidic, neutral and basic drugs from biological fluids. It is particularly useful when a parent drug and metabolites of different functionalities are to be extracted simultaneously, and will provide cleaner extracts than alternative sample preparation techniques such as protein precipitation.

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
