F the many substances that have been found to be mutagenic several are 0 also carcinogenic and considerable evidence has been accumulating to indicate a relationship between these two properties. Nitrogen and sulfur mustards were shown by AUERBACH and ROBSON (1944) to be mutagenic for Drosophila, a finding which has been confirmed by DEMEREC (1947a,b), BURDETTE (1952) and others. Nitrogen musta...

In the title compound, C(14)H(13)NO(2), the aromatic rings attached to the O and N atoms make dihedral angles of 62.65 (9) and 38.28 (11)°, respectively, with the central carbamate group. The benzene rings are oriented at a dihedral angle of 39.22 (10)°. In the crystal, a very weak C-H⋯π inter-action occurs.

The asymmetric unit of the title compound, C(13)H(10)FNO(2), contains two crystallographically independent mol-ecules. The aromatic rings are oriented at dihedral angles of 61.77 (3) and 53.94 (3)° in the two mol-ecules. An N-H⋯O hydrogen bond links the mol-ecules. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains. Weak C-H⋯π inter-actions are also p...

Octadecylammonium in monolayers transforms into a carbamate derivative, as observed by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and 13C nuclear magnetic resonance (NMR) spectroscopy.

In the crystal structure of the title compound, C(3)H(8)N(2)O(2)·H(2)O, the organic mol-ecule exists as zwitterion with the carboxyl group deprotonated and the amino group protonated. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds.
