In the crystal structure of the title compound, C(10)H(8)BrN, the dihedral angle between the two six-membered rings of the quinoline system is 0.49 (16)°. The mol-ecules are packed in a face-to-face arrangement fashion, with a centroid-centroid distance of 3.76 Å between the benzene and pyridine rings of adjacent mol-ecules. No hydrogen bonding is found in the crystal structure.

One of the common presentations to the emergency room is a child with respiratory distress. This could be due to a upper respiratory, lower respiratory or a non respiratory cause. A proper history and a good clinical examination, give the cause for respiratory distress in most of the cases.

This chapter focuses on the biological roles of the glycans contained in glycoproteins. Today we know there is no unifYing function for the carbohydrates present in glycoproteins. They rather span the complete spectrum from being obviously unimportant to being crucial for the survival of an organism. In a crude scheme, their biological functions can be classif ed into two groups. On one hand, t...

In the title compound, C(10)H(8)ClN, the crystal packing shows π-π stacking between the heterocyclic ring and the aromatic ring, with a centroid-centroid distance of 3.819 Å. The crystal studied was a racemic twin, the ratio of the twin components being 0.65 (7):0.35 (7).
