101-57-5 Usage

General Description

4-Anilinobenzenesulfonic acid consists of a benzene ring with an amino group (-NH2) and a sulfonic acid group (-SO3H) attached to the 4-position, making it a member of the sulfonic acid family. 4-Anilinobenzenesulfonic acid is commonly used in the chemical industry as a precursor in the synthesis of various dyes and pigments.

Check Digit Verification of cas no

The CAS Registry Mumber 101-57-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 101-57:
(5*1)+(4*0)+(3*1)+(2*5)+(1*7)=25
25 % 10 = 5
So 101-57-5 is a valid CAS Registry Number.

Fe-MIL-101 modified by isatin-Schiff-base-Co: a heterogeneous catalyst for C-C, C-O, C-N, and C-P cross coupling reactions

Farrokhi, Alireza,Rouzifar, Majid,Sansano, José Miguel,Sobhani, Sara

, p. 19963 - 19976 (2021/11/12)

A metal-organic framework functionalized with a cobalt-complex is preparedviapost-synthetic modification of Fe-MIL-101-NH2. Initially, Fe-MIL-101-NH2reacted with isatin to produce Fe-MIL-101-isatin-Schiff-base, which can anchor the cobalt by the addition of cobalt acetate. The resulting MOF-Co catalyst is characterized by employing multiple techniques. This new modified MOF acts as a heterogeneous and recyclable catalyst for efficient Ullmann, Buchwald-Hartwig, Hirao, Hiyama and Mizoroki-Heck cross-coupling reactions of several aryl halides/phenylboronic acid/phenyltosylate with phenols, anilines/heterocyclic amines, triethyl phosphite, triethoxyphenylsilane and alkenes and generates the expected coupling products in good to high yields.
