3,7-diaminodibenzo[b,d]thiophene 5,5-dioxide CAS NO.6259-19-4

The company is supplying production of designs, syntheses and material ligands.

Jilin Province Yanshen Technology Co.,Ltd. belongs to leading suppliers of the laboratory grade chemicals in China. The Company's skilled professionists specialize on custom synthesis of a wide range of organic compounds with an emphasis on heteroaromatic compounds and plenty of ligands, which are integral part of the research and development in material science especially as COFs (Covalent Organic Frameworks)＆MOFs (Metal-Organic Frameworks).

The company's research and production division especially focus on the synthesis of derivatives with aldehyde , amino, carboxyl, boric acid, halogen, alkyne, hydroxyl , nitro, cyano, nitrogen, sulfur, boric acid, and etc. with the capability to provide these synthetic products in gram to multi-kilogram scale range. Via the reliability of quality, sufficient spot rate and variety, we help our customers to improve the progress of researching and experiments, with the aim to assist the development of emerging chemical industry.

Active cooperation with leading science and business research institutions, universities and chemical＆pharmaceutical industry enterprises, our works ensured quick scientific progress in processing of many commercial research projects.

Ligand types: COFs, MOFs monomers are classified by group as follows:

aldehyde series, amino series, carboxyl series, boric acid series, halogen series,

alkyne series, hydroxyl series, nitro series, cyano series, nitrogen series, sulfur

series, boric acid series, etc.

Customized synthesis: No charge if not successful
