Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers, each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents.
A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when positional isomerism ...
At room temperature, 2,4-dibromophenol is a solid with needle-like crystals. It melts at 38 °C (100.4 °F) and boils at 238.5 °C (461.3 °F). it has a molecular weight of 251.905 g/mol. It is soluble in water, ethanol, ether and benzene and slightly soluble in carbon tetrachloride. [1]
Saccoglossus bromophenolosus is a species of acorn worm (class Enteropneusta) occurring in the northwestern Atlantic Ocean and the northeastern Pacific Ocean. It grows to a length of about 20 cm (8 in) and lives in a burrow in soft sediment in the intertidal and subtidal zones.

The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pK a is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion , and the corresponding salts are called phenolates or phenoxides ( aryloxides according ...
The features need to match different chemical groups with similar properties, in order to identify novel ligands. Ligand-receptor interactions are typically "polar positive", "polar negative" or "hydrophobic". A well-defined pharmacophore model includes both hydrophobic volumes and hydrogen bond vectors.
All animals are chemoheterotrophs (meaning they oxidize chemical compounds as a source of energy and carbon), as are fungi, protozoa, and some bacteria. The important differentiation amongst this group is that chemoorganotrophs oxidize only organic compounds while chemolithotrophs instead use oxidation of inorganic compounds as a source of ...
