Industrial Applications

This compound serves primarily as a synthetic intermediate in the production of sodium-glucose cotransporter 2 (SGLT2) inhibitors, notably in the manufacturing pathway of Tofogliflozin. Its dual carboxylic acid functionality and ortho-bromo group enable sequential functionalization via esterification, amidation, or palladium-catalyzed coupling reactions. Key advantages include:

  • High regiochemical control for selective derivatization
  • Excellent thermal stability under standard processing conditions
  • Compatibility with large-scale GMP-compliant synthesis protocols

Stored in a cool, well-ventilated area away from incompatible materials, 2-Bromoterephthalic acid is typically supplied in 25 kg fiber drums, with custom packaging available upon request. Note: Supply is restricted in jurisdictions where relevant patents are in force.
