25-Thiophene dicarboxylic acid

Application
25-Thiophenedicarboxylic acid may be used as a thiophene based linker in the preparation of magnesium coordination networks.[6]It may also be used as a precursor in the synthesis of 25-bis-benzoxazoyl-thiophene (EBF).It may be used in the synthesis of the following new cobalt(II) thiophenedicarboxylate coordination polymer novel mesogenic thiophene based supramolecular liquid crystals two novel coordination polymers with the formula [Ln2(25-tdc)3(dmso)2]H2On (Ln Tb(III) and Dy(III)) (25-tdc2 25-thiophenedicarboxylate and dmso dimethylsulfoxide)

Purpose
For R&D use onlynot for drug household or other uses.

General Description
25-Thiophenedicarboxylic acid (25-TDCA H2TDC) is an important building block in the preparation of fluorescent brightening agent fungicides and anti-cancer drug. It has been generated by chlorination of adipic acid using thionyl chloride.[5]Due to its diverse coordination modes it is an excellent choice as an aromatic linker to generate coordination networks.[6]The enthalpies of combustion and sublimation of 25-thiophenedicarboxylic acid have been evaluated by rotary-bomb combustion calorimetry.
