This work aimed at the synthesis and characterization of transition compounds with 2-aminoterephthalate ligand in the solid state. The compounds were characterized by simultaneous thermogravimetry-differential thermal analysis (TG-DTA), whereas evolved gas analysis (EGA) was carried out by TG-DSC system coupled to an infrared spectrometer with gas cell. The characterization by these techniques allowed to monitored the thermal behavior, mass loss steps as well as the main gaseous products released in each decomposition step. Furthermore, the thermoanalytical results and titration with EDTA allowed to establish the metal:ligand stoichiometry as 1:1 as well as to determine the water content. From FT-IR results, it was possible to suggest the metal-ligand coordination.

Biotechnology will play a vital role in the overall technological development of the 21st century. Given the rapid speed of globalization coupled with the continuous development of communication technology, small-to-medium-sized enterprises (SMEs) in a variety of high-tech industries in many countries, such as the agriculture biotechnology (agri-biotech)
