CAS:6307-83-1 | 3-Bromo-5-nitrobenzoic Acid

The substance corresponding to CAS 6307-83-1 is 3-Bromo-5-nitrobenzoic Acid, with a molecular formula of C₇H₄BrNO₄ and a molecular weight of 246.01 g/mol. Its melting point is approximately 181.66°C, boiling point 376.76°C, and density 1.893 g/cm³.
3-Bromo-5-nitrobenzoic Acid exists as a light yellow solid, displaying low solubility in water while dissolving readily in solvents such as ethanol, chloroform, and dichloromethane. It serves as a chemical raw material or organic synthesis intermediate for synthetic reactions in the pharmaceutical, pesticide, and dye industries.

Uses:

Medical field: 3-Bromo-5-nitrobenzoic Acid acts as a key intermediate for synthesizing diverse pharmaceuticals, contributing to the construction of drug molecules with specific pharmacological activities. For instance, in the synthesis of antibacterial and anti-inflammatory agents, it provides bromine- and nitro-containing structural fragments that enhance drug-target binding affinity, thereby improving therapeutic efficacy.
Pesticide field: As an essential raw material for developing novel pesticides, it is used to create compounds with high insecticidal, fungicidal, or herbicidal potency, supporting pest and weed management in agricultural practices.
Dye field: This compound is employed in synthesizing dyes with unique color properties. The bromine and nitro groups within its structure influence the electron cloud distribution and conjugated system of dye molecules, altering their hue, stability, and dyeing performance to meet the requirements of various textile materials and dyeing processes.

Method of Preparation:

The preparation of 3-bromo-5-nitrobenzoic acid can be accomplished through the following steps: React benzoic acid with nitrous acid to obtain 3-nitrobenzoic acid. Then, react 3-nitrobenzoic acid with sodium bromide in the presence of ferrous bromide to obtain 3-bromo-5-nitrobenzoic acid.
