Description

Silver chloride (CAS 7783-90-6 ), commonly referenced by its formula AgCl, is an inorganic silver salt used across pharmaceutical, personal care, and biotechnology applications. It functions primarily as an antimicrobial agent and catalyst precursor. The compound delivers controlled silver ion release in formulations and technical processes. In personal care, AgCl is incorporated into deodorant and wound care formulations where sustained antimicrobial activity is required. This material is often preferred over metallic silver due to specific regulatory considerations. Pharmaceutical manufacturers use it as a reference electrode material and as a precursor in the synthesis of other silver compounds. These compounds are essential for various diagnostic and therapeutic products. In biotechnology, silver chloride supports electrode fabrication for biosensors and electrochemical detection systems used in modern laboratories. Catalyst producers also source AgCl as a starting material for preparing silver-based catalysts. These are used in selective oxidation and chemical synthesis processes across the global manufacturing sector. Silver chloride is supplied as a white to off-white powder, with particle size and purity specifications varying by application. Pharmaceutical and analytical grades meeting USP and reagent-grade standards are available. Technical-grade material is also provided for industrial catalyst and pigment applications. Photosensitive handling requirements during storage and transit are standard considerations for procurement and logistics teams. Contact us for supply of Silver chloride Request Quote
