2-Chloro-1,4-dihydroxyanthraquinone is an organic compound with the chemical formula C14H7ClO4. It is a derivative of anthraquinone, a type of quinone, characterized by the presence of a chlorine atom at the 2-position and two hydroxyl groups at the 1 and 4 positions. This yellow crystalline solid is used as an intermediate in the synthesis of various dyes and pigments, particularly those with anthraquinone-based structures. Due to its chemical reactivity, it is important to handle 2-chloro-1,4-dihydroxyanthraquinone with care, as it may have potential health and environmental impacts.

81-53-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81-53-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81-53:
(4*8)+(3*1)+(2*5)+(1*3)=48
48 % 10 = 8
So 81-53-8 is a valid CAS Registry Number.

Polycyclic Hydroxyquinones. Part 22. Diels-Alder Reaction with Chloro Derivatives of Anthracene-1,4,9,10-tetraone

Cano, Pilar,Farina, Francisco,Parellada, M. Dolores,Pascual, Conrado,Prados, Pilar

, p. 1923 - 1928 (2007/10/02)

The Diels-Alder reaction of 2-chloro- and 2,3-dichloro-anthracene-1,4,9,10-tetraones (8) and (9) with substituted buta-1,3-dienes occured at the internal double bond and gave angular adducts.The reaction of quinizarin (4) with chlorine in glacial acetic acid afforded the 2,3,4a,9a-tetrachloro-4a,9a-dihydroanthracene-1,4,9,10-tetraone (17).The cycloaddition of (17) with 2,3-dimethylbuta-1,3-diene (10) gave the fully aromatised linear adduct (19) whereas a reactive diene such as 1-methoxy-3-trimethylsilyloxybuta-1,3-diene (12) afforded the ketone (22), originating from the angular adduct.An explanation for the last result involves the ready halogen elimination in compound (17) to give (9) in the presence of a strongly nucleophilic diene.
