Customer Testimonials

We offer this listing of customer comments, not simply as a testimony to the quality of Exclusive Chemistry's products and services, but as a reminder of the high standard to which we are held.

Exclusive Chemistry undertook a difficult synthesis for us and delivered the product on time and on budget. I would not hesitate to use them again.

Luis Castro, Regulatory Affairs Manager, Gowan Company. USA.

I have had two compounds made by Exclusive Chemistry Ltd. In both cases I was very satisfied with the final product and each had the predicted biological properties. One compound was made right on time and the other suffered a slight delay. In the latter case I found them to be completely responsive and approachable about the delay. In all, my experiences were very positive and I would work with them again in the future and have recommended them to others.

Dr. Stephen Elledge, Department of Genetics, Harvard Medical School. USA.

Clear and quick quotations, delivering of orders in due time, high quality of compounds: mostly >95% and last but not least very fast reaction to our e-mails. Exclusive Chemistry Ltd is one of our best vendors worldwide.

Mr. Tom Newman, Aurora Fine Chemicals Ltd. Austria.

Exclusive Chemistry synthesized to our satisfaction for a fair price 1 g of a substance we urgently needed.

Dr. Erwin Sigel, Department of Biochemistry and Molecular Medicine, University of Bern. Switzerland.

We were very satisfied with the services provided by Exclusive chemistry. They synthesized a good quality chemical compound for us at a fair price.

Dr. Torunn Stalheim, Department of Food safety and Infection Biology, Norwegian School of Veterinary Science. Norway.

We requested from Exclusive Chemistry Ltd to synthesize two small molecules which we had identified in an unbiased screen of a chemical compound library. They synthesized both compounds on time and shipped to us along with NMR data. We verified their MW in our Mass spectrometry facility and found them to be of the correct mass. Overall, the Ex-chemistry scientists were very professional and responded to our e-mails promptly. They even sent us the synthesis steps for one of the compounds when we asked for them.

Dr. Costas Koumenis, Department of Radiation Oncology, University of Pennsylvania School of Medicine. USA

I had a very pleasant experience with Exclusive Chemistry. I needed a custom chemical synthesis and sent out publications about the required chemical synthesis to several different companies. Exclusive Chemistry rapidly responded with a competitive offer. Afterwards they started immediately with the synthesis, perfectly met the proposed time frame, and offered the desired purity of the compound. Communication was very good, and I am completely satisfied with their product.
