4'-Brom-3,5-dichlor-salicylanilid, also known as 4'-bromo-3,5-dichlorosalicylamide, is an organic compound with the chemical formula C7H5BrCl2NO2. It is a derivative of salicylanilide, featuring a bromine atom at the 4' position, and two chlorine atoms at the 3 and 5 positions on the benzene ring. 4'-Brom-3.5-dichlor-salicylanilid is characterized by its white crystalline appearance and is soluble in organic solvents. It is primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of certain herbicides and pesticides. Due to its reactivity and the presence of halogens, it is important to handle 4'-Brom-3.5-dichlor-salicylanilid with care, adhering to proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 6137-44-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6137-44:
(6*6)+(5*1)+(4*3)+(3*7)+(2*4)+(1*4)=86
86 % 10 = 6
So 6137-44-6 is a valid CAS Registry Number.

Relationships between the chemical structure of antimycobacterial substances and their activity against atypical strains. Part 14: 3-Aryl-6,8-dihalogeno-2H-1,3-benzoxazine-2,4(3H)-diones)

Waisser, Karel,Hladuvkova, Jana,Gregor, Jiri,Rada, Tomas,Kubicova, Lenka,Klimesova, Vera,Kaustova, Jarmila

, p. 3 - 6 (1998)

A set of eight derivatives of 6,8-dichloro-3-phenyl-2H-benzoxazine-2,4(3H)-dione and nine derivatives of 6,8-dibromo-3-phenyl-2H-1,3-benzoxazine-2,4(3H)-dione, substituted on the phenyl ring, was prepared by the reaction of the corresponding salicylanilides with ethyl chloroformate. The compounds were evaluated in vitro for antimycobacterial activity against Mycobacterium tuberculosis, Mycobacterium kansasii, and Mycobacterium avium. Their activity increases with increasing hydrophobicity and electron-withdrawing ability of the substituents on the phenyl ring.
