Abstract:
Herein is described a method for the isolation of noncrystalline compounds via adsorption on a solid support. A range of compounds that present as neat oils can be isolated as free-flowing processable solids, including the direct isolation of products from crude reaction streams. This approach was successfully implemented on a multi-kilogram scale for the isolation of a linker fragment as part of an antibody-drug conjugate (ADC) program. This strategy provides a viable alternative in cases where traditional crystallization approaches prove particularly challenging or a through process is not an option.

Chromatography: Introduction
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
