3,3,7,7-tetrakis(4-hydroxyphenyl)pyromellitide is a complex organic compound with the molecular formula C44H24O8. It is characterized by a pyromellitic dianhydride core, which is a cyclic anhydride with four carbonyl groups, to which four hydroxyphenyl groups are attached. 3,3,7,7-tetrakis(4-hydroxyphenyl)pyromellitide is known for its rigid structure and high thermal stability, making it a potential candidate for applications in materials science, such as in the development of high-performance polymers and as a precursor for the synthesis of other complex molecules. The presence of multiple hydroxyl groups also suggests potential uses in the formation of esters or other derivatives, which could have applications in various chemical industries.

6310-67-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6310-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,1 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6310-67:
(6*6)+(5*3)+(4*1)+(3*0)+(2*6)+(1*7)=74
74 % 10 = 4
So 6310-67-4 is a valid CAS Registry Number.

ACYLATION OF PHENOL BY AROMATIC TETRACARBOXYLIC ACIDS AND THEIR DIANHYDRIDES

, p. 1168 - 1173 (2007/10/02)

A series of aromatic dilactones containing 4-hydroxyphenyl substituents were synthesized by the reaction of phenol with pyromellitic, 3,3',4,4'-oxydibenzenetetracarboxylic acids, and their dianhydrides.At increased temperatures condensation at the ortho position of the phenol with the subsequent formation of fluorane structures occurs in addition to para-acylation.As a result of the reaction of 3,3',4,4'-oxydibenzenetatracarboxylic dianhydride with phenol a mixture of three isomeric condensation products is formed.
