Biochem/physiol Actions
TSQ (6-methoxy-8-p-toluenesulfonamido-quinoline) is a cell penetrant and specific fluorescent zinc sensor that preferentially accumulates in islet cells in a zinc content dependent manner. TSQ is commonly used to assess isolated islet purity.
Check Digit Verification of cas no
The CAS Registry Mumber 109628-27-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,2 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109628-27:
(8*1)+(7*0)+(6*9)+(5*6)+(4*2)+(3*8)+(2*2)+(1*7)=135
135 % 10 = 5
So 109628-27-5 is a valid CAS Registry Number.

An efficient photocatalytic method was developed for the remote C5-H bond carboxylation of 8-aminoquinoline amide and sulfonamide derivatives. This methodology uses in situ generated ?CBr3 radical as a carboxylation agent with alcohol and is further extended to a variety of arenes and heteroarenes to synthesize the desired carboxylated product in moderate-to-good yields. The reaction proceeding through a single electron transfer pathway was established by a control experiment, and a butylated hydroxytoluene-trapped aryl radical cation intermediate in high-resolution mass spectrometry was identified.
