3,5-Dimethyl-1,2,4-benzenetriol, also known as pyrogallol, is an organic compound with the chemical formula C6H6O3. It is a white crystalline solid that is soluble in water, alcohol, and ether. 3,5-Dimethyl-1,2,4-benzenetriol is a derivative of benzene, with three hydroxyl groups (-OH) attached to the 1, 2, and 4 positions, and two methyl groups (-CH3) attached to the 3 and 5 positions. Pyrogallol is known for its strong reducing properties and is commonly used as an antioxidant, a developer in photography, and a reagent in various chemical analyses. It is also used in the synthesis of dyes and pharmaceuticals. Due to its potential health risks, pyrogallol is classified as a hazardous substance and requires proper handling and disposal.

4380-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4380-94-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4380-94:
(6*4)+(5*3)+(4*8)+(3*0)+(2*9)+(1*4)=93
93 % 10 = 3
So 4380-94-3 is a valid CAS Registry Number.

A NEW SYNTHESIS OF 1,2,4-BENZENETRIOL CONGENERS

Ozaki, Yutaka,Kim, Sang-Won

, p. 304 - 307 (2007/10/02)

1,2,4-Benzenetriols were synthesized via 4,4-bis(ethylthio)-1,3-cyclohexanediones which were prepared by means of two types of Michael-Claisen condensation starting from methyl bis(ethylthio)acetate or 1,1-bis(ethylthio)-2-propanone.Keywords- annelation; aromatic synthesis; 1,2,4-benzenetriol; methyl bis(ethylthio)acetate; 1,1-bis(ethylthio)-2-propanone; C2+C4 annelation; C3+C3 annelation; Michael-Claisen condensation; α,β-unsaturated ester; dibenzofurandiol

A New Entry to 1,2,4-Benzenetriol Congeners

Ozaki, Yutaka,Kim, Sang-Won

, p. 1199 - 1200 (2007/10/02)

1,2,4-Benzenetriol derivatives were efficiently prepared from annulation of α,α-bis(ethylthio)carbonyl compounds with α,β-unsaturated carbonyl compounds.
