Benzene-1,3-diyl bis(2-hydroxybenzoate), also known as 1,3-isophthalic acid dibenzoate, is a chemical compound with the molecular formula C20H14O6. It is a white crystalline solid that is derived from the esterification of isophthalic acid with benzoic acid. benzene-1,3-diyl bis(2-hydroxybenzoate) is an important intermediate in the production of various polymers, particularly polyesters and polyamides, due to its ability to form strong, stable bonds with other monomers. It is also used in the synthesis of certain pharmaceuticals and dyes. The compound is characterized by its symmetrical structure, which allows for the formation of linear or branched polymer chains, depending on the reaction conditions and the presence of other reactants.

2944-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2944-57-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2944-57:
(6*2)+(5*9)+(4*4)+(3*4)+(2*5)+(1*7)=102
102 % 10 = 2
So 2944-57-2 is a valid CAS Registry Number.

Acylation of Phenols with Salicylic Acid Using Polyphosphoric Acid

Kamat, S. P.,Paknikar, S. K.

, p. 773 - 774 (2007/10/02)

Acylation of 2-naphthol (2), 1-naphthol (6) and resorcinol (11) with salicylic acid (1) in the presence of PPA affords salicylate esters (4, 7, 13 and 14), 1,2-benzoxanthone (5), 3,4-benzoxanthone (8), 3-hydroxyxanthone (12), 2-salicoyl-1-naphthol (9) and 11-hydroxy-12H-benzoxanthen-12-one (10).Compounds (4, 5, 7, 8, 12, 13 and 14) are identical with those obtained by heating a mixture of phenyl salicylate (3) and phenols (2, 6 and 11).

Thermal Conversion of Salol into Xanthone: A Mechanistic Study

Kamat, S. P.,Paknikar, S. K.

, p. 38 - 41 (2007/10/02)

The thermal conversion of salol (1) into xanthone has been rationalized as proceeding via the keto-ketene intermediate (7) which is trapped by phenols (9, 12 and 15).
