2-Furancarboxylic acid, anhydride, also known as phthalic anhydride, is a white, crystalline organic compound with the chemical formula C8H4O3. It is a derivative of 2-furancarboxylic acid, where two molecules of the acid are linked by an anhydride bridge, resulting in the loss of a water molecule. Phthalic anhydride is an important industrial chemical, widely used in the production of plastics, resins, and synthetic fibers, particularly in the manufacture of polyvinyl chloride (PVC) and polyester resins. It is also used as a chemical intermediate in the synthesis of dyes, pharmaceuticals, and other chemicals. The compound is known for its high reactivity and is often used in the formation of esters and amides, which are essential components in various applications.

615-08-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 615-08-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 615-08:
(5*6)+(4*1)+(3*5)+(2*0)+(1*8)=57
57 % 10 = 7
So 615-08-7 is a valid CAS Registry Number.

TBHP/ n -Bu 4 PBr-Promoted Oxidative Cross-Dehydrogenative Coupling of Aryl Methanols: A Facile Synthesis of Symmetrical Carboxylic Anhydride Derivatives

Adib, Mehdi,Pashazadeh, Rahim

supporting information, p. 136 - 140 (2017/12/27)

A transition-metal-free oxidative cross-dehydrogenative coupling reaction has been developed for the preparation of symmetrical carboxylic anhydrides through self-coupling dual C-O bond formations of aryl methanols. In the presence of a catalytic amount of tetrabutylphosphonium bromide (TBPB) as transfer agent and aqueous tert -butyl hydroperoxide (TBHP) as oxidant and reactant, methylene groups of aryl methanols were efficiently oxidized to C=O and coupled with the peroxide oxygen from TBHP to form a diverse array of symmetrical carboxylic anhydride derivatives.
