155631-40-6 Usage
General Description
1,2-Benzenediol, 4,6-dichloro-3-methoxy-(9CI) is a chemical compound that belongs to the family of benzenediols, which are organic molecules with two hydroxyl (OH) groups attached to a benzene ring. This particular compound has two chlorine atoms at positions 4 and 6 on the benzene ring, and a methoxy (CH3O) group attached at position 3. It is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, and has also been studied for its potential antioxidant and antimicrobial properties. However, it is important to handle this compound with care, as it may pose health and environmental risks due to its toxic and potentially hazardous nature.
Check Digit Verification of cas no
The CAS Registry Mumber 155631-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,3 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155631-40:
(8*1)+(7*5)+(6*5)+(5*6)+(4*3)+(3*1)+(2*4)+(1*0)=126
126 % 10 = 6
So 155631-40-6 is a valid CAS Registry Number.

Preparation and properties of chloro-3-methoxycatechols-components of pulp bleaching effluents
Smith, Terrence J.,Wearne, Ross H.,Wallis, Adrian F. A.
, p. 911 - 920 (2007/10/03)
The preparation and properties are given for the seven chlorinated 3-methoxycatechols, several of which have been reported as components of pulp bleaching effluents. The 4- and 6-substituted compounds and the trichloro-3-methoxycatechol were obtained by direct chlorination of the parent catechol or its diacetate. The 5-substituted compound was prepared by the known addition of hydrochloric acid to 3-methoxy-ortho-benzoquinone, and further chlorination gave the 4,5- and 5,6-dichloro isomers. The diacetates of all seven compounds were separated by gas chromatography. Electron impact mass spectra and 1H and 13C NMR data for the diacetates are given.
