YMC Chiral Bulk

Efficient Chiral Separations
Preparative Scale YMC CHIRAL is suitable both for the conventional column separations and also for dynamic axial compression (DAC) columns and simulated moving bed (SMB) systems.
YMC CHIRAL bulk material is available up to several hundred kilograms with YMC's well known high quality, reproducibility and technical support. It provides a significant tool for downstream processing at pilot production scale.
Combined with the surprising cost-efficiency, YMC CHIRAL is regarded highly for development or upscaling of chiral purification processes. In addition, method development is simplified by scouting columns for selectivity screening.
Available Phases are:
- CHIRAL ART Amylose-C (Neo)
- CHIRAL ART Amylose-SA
- CHIRAL ART Cellulose-C
- CHIRAL ART Cellulose-SB
- CHIRAL ART Cellulose-SC
- CHIRAL ART Cellulose-SJ

For the competitor’s product, loading amount of more than 0.1 mg was not possible because the enantiomeric excess of the 2nd peak was already less than 98%ee with a loading amount of 0.1 mg.

The calculated maximum loading amount on CHIRAL ART Cellulose-SB of 1.6 mg was 10 times
larger than that obtained for the competitor’s product due to the large differences in the peak
shapes, even though the interval between repeat injections was higher!

Linear scale-up was performed using the appropriate scale-up factors. The Dynamic Axial Compression Column self-packed with CHIRAL ART Cellulose-SB 10 μm can be easily and linearly scaled-up for a greater purification scale. The final productivity is 366 and 390 mg/h respectively for peak 1 and 2.
YMC Database
A selection of chiral applications can be foundat http://ymc.de/applications.html. Here, you can search for chiral applications already known for your compounds.
Test Columns or Screening Kits
You can request a test column to initially test a chiral column before finally buy it if it works for your application. If the column is not suitable, simply return it without any further requirements.
Alternatively you can choose one of the YMC method development kits (see page 13) or requesta customised screening kit with 2, 3, 4 or 5 different CHIRAL ART phases. You only need to contact your local YMC contact for details.
