In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C4H2Cl2N2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1837-55-4, name is 3,5-Dichloropyridazine. In an article，Which mentioned a new discovery about 1837-55-4
This application discloses compounds according to generic Formula I: wherein the variables are defined as described herein, and which inhibit Btk. The compounds disclosed herein are useful to modulate the activity of Btk and treat diseases associated with excessive Btk activity. The compounds are further useful to treat inflammatory and auto immune diseases associated with aberrant B-cell proliferation, such as rheumatoid arthritis. Also disclosed are compositions containing compounds of Formula I and at least one carrier, diluent or excipient.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1837-55-4, help many people in the next few years.HPLC of Formula: C4H2Cl2N2
