2-Amino-3,4,5,6-tetra-fluoro-benzoic acid.

ABSTRACT: The asymmetric unit of the title compound, C(7)H(3)F(4)NO(2), obtained as an inter-mediate in the synthesis of a coupling reagent, contains four independent and conformationally similar mol-ecules. The amine H atoms form both intra-molecular and inter-molecular N-H⋯O(carbox-yl) hydrogen bonds which, together with inter-molecular O-H⋯O(carbox-yl) hydrogen bonds and N-H⋯F associations form ribbon structures along the a axis.
