What is Silver chloride?

Silver chloride (CAS 7783-90-6), also referenced by its formula AgCl, is an inorganic silver salt.

Where is Silver chloride used?

  • Pharmaceuticals: reference electrode material and precursor in the synthesis of other silver compounds
  • Personal care: antimicrobial agent in deodorant and wound care formulations
  • Biotechnology: electrode fabrication for biosensors and electrochemical detection systems
  • Catalyst production: starting material for silver-based catalysts used in selective oxidation and chemical synthesis
  • It delivers controlled silver ion release in formulations and technical processes.

Good to know: Often preferred over metallic silver due to specific regulatory considerations. Photosensitive handling requirements during storage and transit are standard considerations for procurement and logistics teams.

Commercial specifications

  • Particle size and purity specifications vary by application
