For chemists, formulators, and procurement specialists, a thorough understanding of a chemical's properties is foundational to its effective application and sourcing. 2-Amino-4-bromobenzoic acid (CAS 20776-50-5) is a compound whose specific characteristics make it invaluable across various industries, particularly in organic synthesis, pharmaceuticals, and agrochemicals. As a committed manufacturer and supplier, we aim to provide clarity on its key properties to aid your decision-making process.

Physical Characteristics: Appearance and Form
Typically, 2-Amino-4-bromobenzoic acid is presented as a light yellow to white powder or crystalline solid. This physical form is consistent with many organic intermediates and is important for handling, weighing, and dissolution during synthesis. The consistency in its appearance, as reported by reputable suppliers, is often an indicator of controlled manufacturing processes.

Chemical Reactivity and Functional Groups:
The compound's molecular structure, C7H6BrNO2, features an aromatic ring substituted with a carboxylic acid group (-COOH), an amino group (-NH2), and a bromine atom (-Br). This trifunctional nature dictates its reactivity:

  • The carboxylic acid group imparts acidic properties and can undergo esterification, amide formation, and salt formation.
  • The amino group is basic and nucleophilic, enabling reactions such as acylation, alkylation, and participation in diazotization.
  • The bromine atom is an electrophilic site susceptible to nucleophilic aromatic substitution and is crucial for various cross-coupling reactions (e.g., Suzuki, Heck, Ullmann).

These properties make 2-Amino-4-bromobenzoic acid an excellent scaffold for building more complex molecular structures. Its reactivity profile is key to its utility as an intermediate.

Solubility and Stability:
While described as slightly soluble in water, its solubility can be enhanced in polar organic solvents. Understanding its solubility is critical for selecting appropriate reaction media. The compound is generally stable under recommended storage conditions, typically in a cool, dry, and well-ventilated place, away from strong oxidizing agents. This stability ensures its usability over time when stored correctly.

Melting Point and Other Properties:
The melting point of 2-Amino-4-bromobenzoic acid is reported in the range of 230-234°C. This relatively high melting point indicates a stable crystalline structure. Other physical data, such as density and predicted boiling points, are available from chemical databases and manufacturers, providing a comprehensive profile for R&D and safety assessments.
