Biocompatible Iron (III) Carboxylate MOF – KRICT F100 (F-Free Form of MIL-100(Fe))

Iron trimesate MOF KRICT F100, a modified version of MIL-100(Fe), has shown to be a promising material for biomedical applications and selective gas/liquid separation


Metal-Organic Frameworks (MOFs) are unique materials, having a basic structure consisting of clusters linked to each other with organic ligands.  The structure of KRICT F100 (Catalog #26-2340) is built with iron trimesate, and is a fluorine-free version of MIL-100(Fe). 


KRICT F100 has been shown to be biocompatible and hydrothermally stable in boiling water. It can be used for the Pechmann reaction, which leads to the formation of coumarins - naturally occurring substances with wide applications in the pharmaceutical industry.  Iron trimesate based MOFs can also be used as strong Lewis acid catalysts for Friedel–Crafts acylations, Beckmann rearrangement of oximes, Knoevenagel condensation, Prins reaction (addition aldehydes or ketones to alkenes) and annulation reaction.  These widely used reactions have a broad range of applications in fine chemistry and life sciences, and may open novel applications for fluorine-free KRICT F100 MOFs in the biomedical field.1 In addition, large-pored iron trimesate can be reduced under controlled conditions to generate sites that strongly interact with unsaturated gas molecules and enable selective gas absorption and separation.2-4


KRICT F100 product could be provided as beads, or as a slurry solution for coatings.

KRICT F100 is available in two forms: dark brown hydrated [Fe3O(H2O)2(OH){C6H3(CO2)3}2]· nH2O (n > 12), and pale brown dehydrated [Fe3O(OH){C6H3(CO2)3}2].  The pale brown powder has a specific surface area of 2120 m2/g (Langmuir) and 1950 m2/g (BET). The pore volume is 1.075 cm3/g
