Quinoline-5-carboxylic acid is an important raw material and intermediate used in organic synthesis, pharmaceuticals agrochemicals and dyestuff fields.

Quinoline-5-carboxylic acid could synthesize a thermally stable microporous metal-organic framework (MOF Ni-Qc-5) to enhance the separation of CH4 against N2. The highest adsorption CH4 uptake (1.3 mmol/g) was achieved compared to N2 (0.28 mmol/g). Compared with other MOF materials, Ni-Qc-5 possessed very low adsorption energy and high selectivity at low pressure of 0.1 bar[1].
