A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Quality Control of: 4-(4-Bromophenyl)-1-(methylsulfonyl)piperidine, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 622386-94-1, Name is 4-(4-Bromophenyl)-1-(methylsulfonyl)piperidine, molecular formula is C12H16BrNO2S. In a Patent, authors is ，once mentioned of 622386-94-1
This invention is directed generally to proteinase (also known as “protease”) inhibitors, and, more particularly, to piperidinyl-and piperazinyl-sulfonylmethyl hydroxamic acids that, inter alia, inhibit matrix metalloproteinase (also known as “matrix metalloprotease” or “MMP”) activity and/or aggrecanase activity. Such hydroxamic acids generally correspond in structure to the following formula: (wherein A1, A2, Y, E1, E2, E3, and Rx are as defined in this specification), and further include salts of such compounds. This invention also is directed to compositions of such hydroxamic acids, intermediates for the syntheses of such hydroxamic acids, methods for making such hydroxamic acids, and methods for treating conditions (particularly pathological conditions) associated with MMP activity and/or aggrecanase activity. ”
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 622386-94-1, help many people in the next few years.Quality Control of: 4-(4-Bromophenyl)-1-(methylsulfonyl)piperidine
