3-Bromonaphthalene-1,2-dione is an organic compound with the chemical formula C10H5BrO2. It is a halogenated derivative of naphthalene-1,2-dione, where a bromine atom is attached to the third carbon position of the naphthalene ring. This yellow crystalline solid is characterized by its unique chemical structure, which features a naphthalene core with two carbonyl groups (C=O) at the 1 and 2 positions, and a bromine atom at the 3 position. 3-Bromonaphthalene-1,2-dione is used as an intermediate in the synthesis of various organic compounds, particularly in the pharmaceutical and chemical industries. Its properties include a melting point of 156-160°C and limited solubility in water, but it is soluble in organic solvents such as ethanol and acetone. Due to its reactivity and potential applications, it is essential to handle 3-bromonaphthalene-1,2-dione with care, following proper safety protocols.

7474-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7474-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,7 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7474-83:
(6*7)+(5*4)+(4*7)+(3*4)+(2*8)+(1*3)=121
121 % 10 = 1
So 7474-83-1 is a valid CAS Registry Number.

Investigations into the nitric acid mediated dehalonitration of halophenols

Adimurthy, Subbarayappa,Vaghela, Sanjay S.,Vyas, Punita V.,Bhatt, Anjani K.,Ramachandraiah, Gadde,Bedekar, Ashutosh V.

, p. 6393 - 6395 (2007/10/03)

A reaction of nitric acid with bromophenols and iodophenols results in substitution of the halogen with a nitro group. The study indicates moderate reactivity for bromophenols and iodophenols, while chlorophenols were found to be sluggish in this reaction.
