Cr(III) ions to finally obtain ion-selective sorbent able to selectively combine with Cr(III) ions from water when coexisting with other similar metalions. The azo dye derived from resorcinol and p-aminobenzoic acid was prepared and then linked to the chitosan amino groups by amide linkages utilizing EDC/NHS coupling agent.

Synthesis, characterisation and anti-diabetic activities of triorganotin(IV) azo-carboxylates derived from amino benzoic acids and resorcinol: Crystal structure and topological study of a 48 membered macrocyclic-tetrameric trimethyltin(IV) complex
Abstract Triorganotin(IV) complexes of azo-carboxylic acids derived from amino benzoic acids and resorcinol were synthesized by the reaction of 2/4-(2,4-dihydroxy-phenylazo)-benzoic acids with appropriate triorganotin(IV) chlorides [R = Me (1 and 3), Ph (2 and 4) and Bu (5)] in presence of triethylamine. The characterisation of the complexes was accomplished by elemental analyses, UV, IR and multinuclear
