XinXiang Runyu Material Co., Ltd. The quality inspection department of Runyu was established at the beginning of the company, and gradually expanded the team, equipment and technology with the growth of Runyu. Now the analysis and testing center has advanced ventilation and purification system, with a number of testing instruments, such as GCMS, HPLC, GC, catalyst evaluation device, no water and no oxygen glove box, etc.. Our continuous growth, only to provide customers with the best quality products and services.With the improvement of environmental protection and technical requirements, the research and development investment of different pharmaceutical and new materials enterprises continues to increase, and the demand for catalyst continues to increase.Runyu has a relatively complete domestic catalyst products, which will provide more flexible catalyst application options for the downstream enterprises of the industrial chain.

USES:

SPhos 2-Dicyclohexylphosphino-2′,6′-dimethoxybiphenyl is an air-stable, electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions.

SPhos may be used as a ligand in the following processes:

● Palladium catalyzed Suzuki-Miyaura cross-coupling reaction between Boc-protected aminomethyltrifluoroborate and aryl chlorides or hetaryl chlorides to form the corresponding aminomethylarenes.

● Palladium catalyzed Suzuki-Miyaura cross-coupling reaction between 4-methyl-substituted piperidinylzinc reagent and different aryl or heteroaryl iodides to form various substituted piperidines.

● Intramolecular Suzuki-Miyaura coupling to form the 18-membered macrocyclic ring during the multi-step synthesis of riccardin C.

Utilized in conjunction with palladium to form a highly active catalyst for C-N bond formation.

Highly universal ligand for Suzuki-Miyaura coupling; aryl chlorides, hindered biaryls, heterobiaryls.

Quality Control

We have QC person stay on the production lines do to the inspection.All products must have been inspected before delivery.

1. All raw material checked once it arrive our factory.

2. We perform sampling for all production steps.

3. All packing details checked during production.

4. All production quality tests will complete the final inspection before shipment.
