Custom Synthesis
Custom synthesis has always been a significant part of VXCHEM’s production. In the field of custom synthesis, VXCHEM has its own professional R&D team who dedicated to effective realization of multi-step synthesis in laboratory, pilot and production scale. Thanks to the efficiency of our R&D team and the unreserved support from our business partners, we are proud of our ability to give quick response and solution to customer’s questions. We are dealing with custom synthesis, compound libraries, intermediates and building blocks for research and development.
The preparation of chemicals is always performed with utmost care under the guidelines of our quality control. The products are controlled by analytical methods like HPLC, TLC and NMR as well as by chemical analytical methods. This enables us to ensure the highest purity of the products and to fulfill the specifications of our customers.
The attached list of chemical processes will show you the wide range of reactions that we are able to apply to the synthesis of our products.
Please do not hesitate to contact us for quotations on our products. Enquiries will always be treated confidentially.In fact, if a compound that we can’t synthesize, there will not be in the whole of China.

I am looking for a price quote for 10g of 2-methylamino-1-p-tolylpropan-1-one to be synthesized and sent to the United States immediately for purposes of my research. Please get back to me if this would be possible.
Thank you,
-Matt Wilcox
We need the following two compounds:
N-{1-[2-(furan-2-yl)-2-hydroxyethyl]piperidin-4-yl}-N-phenylpropanamide 100g >98%
N-{3-methyl-1-(2-(furan-2-yl)ethyl)piperidin-4-yl}-N-phenylpropanamide 100g >98%
Both of these compounds can be made relatively easily in three short steps with minor work-up, starting with 4-piperidone / 3-methyl-4-piperidone. We can provide detailed notes to help facilitate smooth and high-yielding synthesis.
Plz send 30kg Clopidogrel sulfate Form 1 USP follow the last Standard as soon as possible, CAS 120202-66-6

Hello,
We are looking for a company that can synthesize a relatively simple product for us.
The product needed is Loperamide Propionyl Ester HCl, the product of the esterification of Loperamide HCl with Propionic Anhydride.
Please quote us a price on a sample quantity. If our research continues as planned, we will likely require much larger quantities in the future.
Thank you,
