This article delves into the chemical properties and crucial applications of this compound, emphasizing why its procurement from reputable manufacturers is vital for the pharmaceutical industry.

Chemical Profile and Properties

5-Bromo-2-chlorobenzoic acid is an organic compound characterized by a benzene ring substituted with a bromine atom, a chlorine atom, and a carboxylic acid group. Its molecular formula is C7H4BrClO2, and it typically presents as a white to off-white powder. Key physical properties, such as a melting point around 154-156 °C, are crucial for its handling and reaction processes. The presence of both bromine and chlorine atoms, along with the reactive carboxylic acid group, makes it a versatile intermediate for various chemical transformations.

Key Applications in Pharmaceutical Synthesis

The primary significance of 5-Bromo-2-chlorobenzoic acid lies in its role as a precursor for several important active pharmaceutical ingredients (APIs). The most prominent examples include:

  • Dapagliflozin: A selective sodium-glucose cotransporter-2 (SGLT2) inhibitor used to treat type 2 diabetes, cardiovascular disease, and chronic kidney disease. The synthesis of Dapagliflozin heavily relies on 5-Bromo-2-chlorobenzoic acid as a key starting material.
  • Empagliflozin: Another prominent SGLT2 inhibitor with similar therapeutic applications to Dapagliflozin. The efficient synthesis of Empagliflozin also utilizes 5-Bromo-2-chlorobenzoic acid, underscoring its importance in modern diabetes management.

Beyond these major applications, 5-Bromo-2-chlorobenzoic acid can also serve as an intermediate in the synthesis of other fine chemicals and in research and development efforts exploring new therapeutic compounds. Its carefully balanced reactivity allows chemists to selectively modify parts of the molecule, leading to a diverse range of downstream products.

The Importance of Sourcing from Reliable Suppliers

For pharmaceutical manufacturers, the quality and consistency of intermediates directly impact the efficacy, safety, and regulatory compliance of the final drug product. Therefore, sourcing 5-Bromo-2-chlorobenzoic acid from trusted manufacturers and suppliers is paramount. When you are looking to buy this compound, consider:

  • Purity Standards: Always demand a high purity level (e.g., ≥98% or 99%) with a detailed Certificate of Analysis.
  • Manufacturing Capacity: Ensure the supplier can meet your volume requirements, from R&D to commercial scale.
  • Regulatory Compliance: Verify that the supplier adheres to relevant quality management systems and industry standards.
  • Competitive Pricing: While quality is key, exploring options from manufacturers in regions like China can offer significant cost advantages for bulk purchases.

Engaging with manufacturers who specialize in pharmaceutical intermediates ensures that you receive products that meet stringent quality controls. Companies offering this compound often provide competitive pricing for bulk orders and can support custom synthesis needs.

Conclusion

5-Bromo-2-chlorobenzoic acid is a cornerstone in the synthesis of essential diabetes medications like Dapagliflozin and Empagliflozin. Its unique chemical structure and reactivity make it an invaluable intermediate for the pharmaceutical industry. For researchers and manufacturers seeking to source this critical compound, partnering with reliable suppliers who can guarantee high purity, stable supply, and competitive pricing is essential for driving innovation and ensuring patient access to vital treatments.
