Although capable of very high resolution, RP-HPLC is often limited by low column loading capacity, therefore demanding a significant time investment for peptide purification. As an alternative strategy, reversed-phase flash chromatography can also be used to purify synthetic peptides. The larger particle size used in flash column chromatography enables much larger loading capacity, thereby significantly reducing the time required for peptide purification.

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.

Oftentimes, aqueous samples collected contain varying amounts of suspended solids or sediment strictly due to either the source of the water being sampled or improper sampling techniques. In any circumstance, samples with high amounts of particulates or sediment have proven challenging to extract using EPA Method 3535 Solid Phase Extraction (SPE).

Dioxins are of great environmental concern due to their teratogenic, mutagenic, and carcinogenic impact. These lipophilic compounds bioaccumulate in humans and wildlife and can have half lives of up to 132 years, making them persistent organic pollutants (POPs). Traditional SPE requires a filtration step to remove particulates when using SPE cartridges, because of clogging issues.

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.

Traditional RP-HPLC techniques not always critical because improvements in solid-phase peptide synthesis techniques over the years (microwave heating and ChemMatrix® solid phase supports) have reduced the burden on downstream purification steps. Mass directed flash purification can be a viable alternative to more expensive (and lower capacity) semi- or prep-scale RP-HPLC methods.
