4-Chloro-1,2,3-trihydroxybenzene, also known as 4-chlorogallol, is an organic compound with the chemical formula C6H5ClO3. It is a derivative of benzene, featuring three hydroxyl groups (-OH) at the 1, 2, and 3 positions, and a chlorine atom (-Cl) at the 4 position. This white crystalline solid is soluble in water, ethanol, and ether. 4-Chloro-1,2,3-trihydroxybenzene is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also used as an antioxidant and a reagent in analytical chemistry. Due to its reactivity, it is sensitive to light and heat, and should be stored in a cool, dark place.

3598-34-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3598-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,9 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3598-34:
(6*3)+(5*5)+(4*9)+(3*8)+(2*3)+(1*4)=113
113 % 10 = 3
So 3598-34-3 is a valid CAS Registry Number.

Preparation of chlorosyringols and chloropyrogallols - Components of pulp bleaching effluents

Smith,Wearne,Wallis

, p. 921 - 930 (2007/10/03)

The preparation and properties of chlorosyringols and chloropyrogallols, components of pulp bleaching effluents, and their acetates are given. The compounds are obtained mainly by direct chlorination of both phenols or of syringol acetate with various chlorinating reagents. 5-Chloropyrogallol and 4,5-dichloropyrogallol were the products of demethylation of 5-chloro-3-methoxycatechol acetate and 4,5-dichloro-3-methoxycatechol acetate, respectively. The acetates of all ten chloro compounds were separated by gas chromatography. Electron impact mass spectra and 1H and 13C NMR data for the acetates are given.
