Lichen planus is a chronic recurrent rash that is due to inflammation in the skin and mucous membranes. The rash is characterized by small, flat-topped, many-sided (polygonal) bumps that can grow together into rough, scaly plaques on the skin.
Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger pests such as possum.ompound 1 is the starting ester needed to synthesize brodifacoum. To obtain this starting compound a simple Wittig condensation of ethyl chloroacetate with 4â-bromobiphenylcarboxaldehyde was accomplished.
Brominated vegetable oil (BVO) is a complex mixture of plant-derived triglycerides that have been reacted to contain atoms of the element bromine bonded to the molecules. Brominated vegetable oil is used primarily to help emulsify citrus-flavored soft drinks, preventing them from separating during distribution. Brominated vegetable oil has been used by the soft drink industry since 1931, generally at a level of about 8 ppm. Careful control of the type of oil used allows bromination of it to produce BVO with a specific density (1.33 g/mL). As a result, it can be mixed with less-dense flavoring agents such as citrus flavor oil to produce a resulting oil whose density matches that of water or other products.
