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]
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 ...
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 loaded protein is then tri-brominated with the flavin-dependent halogenase, Bmp2 (Hal), becoming 2,3,4,5-tetrabromopyrrole. Next, Bmp8 (D), a unique thioredoxin-like dehalogenase, removes the C-2 bromine of tetrabromopyrrole, [14] which then allows for coupling to the previously described 2,4-dibromophenol via the cytochrome P450 enzyme ...
The metabolome reflects the interaction between an organism's genome and its environment. As a result, an organism's metabolome can serve as an excellent probe of its phenotype (i.e. the product of its genotype and its environment).
In chemistry, bifunctionality or difunctionality is the presence of two functional groups in a molecule. A bifunctional species has the properties of each of the two types of functional groups, such as an alcohol (−OH), amide (−CONH 2), aldehyde (−CHO), nitrile (−CN) or carboxylic acid (−COOH). Many bifunctional species are used to ...
