3-Aminophenylboronic acid monohydrate
In the title compound, C(6)H(8)BNO(2)·H(2)O, the almost planar boronic acid mol-ecules (r.m.s. deviation = 0.044 Å) form inversion dimers, linked by pairs of O-H⋯O hydrogen bonds. The water mol-ecules link these dimers into [100] chains by way of O-H⋯O hydrogen bonds, and N-H⋯O links generate (100) sheets.
متن کامل2-Methyl-3-(3-methylphenyl)acrylic acid
The crystal structure of the title compound, C(11)H(12)O(2), consists of dimers which are formed due to inter-molecular O-H⋯O hydrogen bonding. The dimers are linked to each other by C-H⋯O hydrogen bonds, where C-H belongs to the benzene ring and the O atom is of a carbonyl group of an adjoining mol-ecule. There exist two inter-molecular C-H⋯O hydrogen bonds which form five-membered rings. Ther...
متن کامل3-Acetylbenzoic acid
In the crystal structure of the title compound, C(9)H(8)O(3), essentially planar mol-ecules [the carboxyl group makes a dihedral angle of 4.53 (7)° with the plane of the ring, while the acid group forms a dihedral angle of 3.45 (8)° to the ring] aggregate by centrosymmetric hydrogen-bond pairing of ordered carboxyl groups. This yields dimers which have two orientations in a unit cell, creating ...
متن کامل3-(Phenylcarbamoyl)acrylic acid
In the title compound, C(10)H(9)NO(3), the dihedral angle between the phenyl ring and the amide group is 10.8 (2)°. The C=O and O-H bonds of the carboxyl group adopt an anti orientation and an intra-molecular O-H⋯O hydrogen bond closes an S(7) ring. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into C(7) chains propagating in [101]. The packing is consolidated by C-H⋯O inter-actions,...
متن کامل3-hydroxyanthranilic Acid Metabolism
The participation of 3-hydroxyanthranilic acid as an intermediate in the biosynthesis of nicotinic acid from tryptophan was first demonstrated in certain mutant strains of Neurospora in 1948 by Bonner (1) and by Mitchell and Nyc (2). In addition, Mitchell et al. (3) found that 3-hydroxyanthranilic acid can replace nicotinic acid in the nutrition of the rat. In 1946 Singal et al. (4) noted a sub...
