User report: Flash instruments. Chugai Pharmaceutical uses Biotage flash chromatography products for drug discovery research. When deciding to convert from manual open-column procedures to automated systems, they chose successive generations of Biotage products, ranging from the Flash+® packed column to the Biotage® Horizon, SP1, Isolera™ Spektra, and Isolera™ Dalton automated flash chromatography systems.

Normal-phase flash purification is commonly used by organic chemists in pharmaceutical drug discovery and
process development labs. However, for many synthesized products (e.g. peptides, nucleotides and basic
drug candidates) purification on standard flash silica is not an option due to irreversible adsorption, chemical
interaction and/or solubility issues. Reversed-phase flash purification is an excellent solution for these applications. Yet, this technique has been used sparingly because of perceived lower loading capacity, higher
operating pressures and a scarcity of publications addressing reversed-phase flash chromatography.

For pilot and production scale purification drugs, the use of a large particle-size media is common. Improving the purification throughput is limited by the media’s large particle size. Such a case was recently encountered when a pharmaceutical company attempted to improve the efficiency of a large-scale purification. In their current process, the use of a 350-600 µm polystyrene-type resin resulted in a lengthy purification cycle and low separation efficiency. However, the labile properties of the targeted component required a shorter purification cycle and high purification.

In mass detection, the presence of ions can suppress peaks
from the analytes of interest. This study concludes that
Isolera™ Dalton performs successful separations even with
ions present in the sample.

Peptide purification using standard reversed phase HPLC methods are hampered by low loading capacity, resulting in purifications that demand significant time investment. Recently, the use of reversed phase flash chromatography has increased in popularity for peptide purification due to the significant reduction of purification time,
enabled by the increased loading levels of the larger stationary phase particles. Resolution, though, is somewhat diminished with the larger particle size, demanding creative techniques to retain a highly pure peptide product.

In medicinal chemistry, organic synthesis will generate by-products with similar chemistry to the product. Separating these impurities from the product often becomes a challenge that often only prep HPLC can achieve.
In this poster, we discuss how using sample dry loading with a cation exchange scavenger media with flash chromatography
improves product purity by removing many of the impurities.

Fragrance compounds, being invisible to UV, can be
elusive and difficult to isolate. In this application, a four
component mixture of fragrance compounds was purified
using Accelerated Chromatographic Isolation™ (ACI) and
identified by mass detection.
