1195-33-1 Usage
General Description
Benzenesulfinic acid, 4-bromo- is an organic compound containing a benzene ring with a sulfinic acid functional group and a bromine atom attached to the fourth carbon of the benzene ring. It is a colorless to pale yellow solid that is soluble in water and commonly used as a reagent in organic synthesis. Benzenesulfinic acid, 4-bromo- is known for its ability to react with a range of organic and inorganic compounds, making it a versatile intermediate in the production of various pharmaceuticals, dyes, and agricultural chemicals. It is also used as a precursor in the synthesis of other organic compounds. Due to its reactivity and potential health hazards, proper safety precautions should be taken when handling and using benzenesulfinic acid, 4-bromo-.
Check Digit Verification of cas no
The CAS Registry Mumber 1195-33-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1195-33:
(6*1)+(5*1)+(4*9)+(3*5)+(2*3)+(1*3)=71
71 % 10 = 1
So 1195-33-1 is a valid CAS Registry Number.

, p. 319 - 328 (2007/10/03)
The rates of morpholine-desulfonylation of 2,4-dinitrophenyl-4'-substituted phenylsulfones (1-6: aryl = 4-Y-C6H4, Y = H, CH3, OCH3, Br, Cl and NO2) have been measured in methanol at different temperatures (25 deg C-40 deg C) and the activation parameters were calculated.A good Hammett correlation was obtained with ρ values of 0.43-0.75.The plot ΔH(excit.) versus ΔS(excit.) gave an isokinetic temperature at 339 deg K.
