4,4'-Butanediyldioxydibenzoic acid, also known as 4,4'-oxybis(benzoic acid), is a white crystalline solid with the chemical formula C14H12O6. It is an organic compound derived from benzoic acid, featuring a butane-1,4-diyl group connecting two benzoic acid units through their carboxyl groups. This diacid is used as a monomer in the synthesis of various polymers, such as poly(butylene terephthalate) (PBT), a thermoplastic polymer known for its high strength, heat resistance, and chemical stability. It is also used in the production of certain types of polyesters and as a chemical intermediate in the pharmaceutical and chemical industries. The compound is typically synthesized through the esterification of benzoic acid with butane-1,4-diol, followed by hydrolysis to yield the diacid.

3749-77-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3749-77-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3749-77:
(6*3)+(5*7)+(4*4)+(3*9)+(2*7)+(1*7)=117
117 % 10 = 7
So 3749-77-7 is a valid CAS Registry Number.

Biological evaluation of bisbenzaldehydes against four Mycobacterium species

Cappoen, Davie,Forge, Delphine,Vercammen, Frank,Mathys, Vanessa,Kiass, Mehdi,Roupie, Virginie,Anthonissen, Roel,Verschaeve, Luc,Vanden Eynde, Jean Jacques,Huygen, Kris

, p. 731 - 738 (2013/07/25)

A series of bisbenzaldehydes and structurally related analogs, conveniently synthesized via microwave-assisted reactions, were evaluated in vitro against drug susceptible and multi-drug resistant Mycobacterium tuberculosis, against virulent Mycobacterium bovis, against Mycobacterium ulcerans and against two Mycobacterium avium subspecies. Among the 33 substances that were tested, compound 12, i.e. 4,4′-[1,12-dodecanediyl(oxy)]bisbenzaldehyde, emerged as the most promising hit. Its activity was further confirmed in an intracellular growth inhibition assay of M. tb in murine J774 A.1 macrophages. None of the compounds showed significant cytotoxicity on human C3A hepatocytes in a neutral red dye uptake assay and no genotoxicity or mutagenicity was observed as demonstrated by a VITOTOX test and confirmed with a comet assay.
