In the title compound, C(11)H(13)NO(3)S, the dihedral angle between the benzyl and carbamate groups is 12.67 (10)°. The S atom and the carbonyl O atom are positioned anti to each other. In the crystal, pairs of N-H⋯S hydrogen bonds link mol-ecules into inversion dimers.

Structures of tert-butylcarbamate ions in the gas-phase and methanol solution were studied for simple secondary and tertiary carbamates as well as for carbamate-containing products and internal standards for lysosomal enzyme assays used in newborn screening of a α-galactosidase A deficiency (Fabry disease), mucopolysaccharidosis I (Hurler disease), and mucopolysaccharidosis II (Hunter disease)....

In the title mol-ecule, C(8)H(8)N(2)O(4), the nitro and meth-oxy-carbonyl groups are twisted from the plane of aromatic ring by 5.1 (1) and 6.2 (1)°, respectively. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules related by translation along the b axis into chains. Weak inter-molecular C-H⋯O inter-actions link further these chains into sheets parallel to the bc plane.

The asymmetric unit of the title compound, C(14)H(13)NO(3), contains two crystallographically independent mol-ecules, in which the aromatic rings are oriented at dihedral angles of 75.64 (3) and 83.14 (3)°. An N-H⋯O hydrogen bond links the two mol-ecules. Weak intramolecular C-H⋯O inter-actions are observed in the two mol-ecules. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O inter-a...

The title compound, C(13)H(12)N(2)O(2), was obtained by the reaction of 4-amino-pyridine and benzyl chloro-formate in tetra-hydro-furan. The crystal structure contains N-H⋯N hydrogen bonds between two unique mol-ecules within layers and anti-parallel C-O⋯O-C inter-actions [O⋯O = 3.06 (3) Å] between the two mol-ecules of the asymmetric unit.
