2208-15-3 - Introduction
acid is an organic compound with the chemical formula C11H7BrO3 and its molecular weight is 271.08g/mol. The following is an introduction to its nature, use, preparation and safety information:
Nature:
-Appearance: acid is a white to light yellow crystal or powdery solid.
-Solubility: It is soluble in some organic solvents, such as alcohols and ketones, and insoluble in water.
-Melting point: Its melting point range is 190-195 ° C.
Use:
-Reagent in chemical reactions: acid can be used as a reagent for organic synthesis reactions, such as asymmetric synthesis, coupling reactions and acylation reactions.
-Intermediate of fluorescent dyes: It can also be used as a synthetic intermediate of fluorescent dyes.
Method: The preparation of
-bromide can generally be carried out by the following steps: First, 2-naphthoic acid is reacted with bromine in the presence of acetic acid and sodium sulfite to obtain 2-bromo-naphthoic acid. Then, 2-bromo-naphthoic acid was reduced by controlling the reaction conditions to give oxonium acid.
Safety Information:
-The specific hazards and toxicity of acid need to be further studied, so it is necessary to pay attention to personal protection and safe operation measures when using this compound. Inhalation, ingestion or contact with skin must be avoided. Wear appropriate personal protective equipment, such as respiratory protection, protective gloves and goggles, during the operation, and ensure that the experimental environment is well ventilated.
Please note that this is only a general overview, and the specific experimental conditions and safety operation guidelines need to be determined according to the actual situation. Before any chemical research or use of chemicals, it is recommended to refer to the relevant chemical literature and to operate under the guidance of an experienced person.
