High-Purity Silver Chloride from Aure Chemical – Your Trusted Source
Silver chloride, AgCl, CAS No. 7783-90-6, is a classic and widely used silver(I) compound known for its photosensitivity, low solubility, and applications in analytical chemistry, photography, and materials science. Supplied by Aure Chemical as fine white to slightly grayish powder with high silver content (approximately 75–76% Ag), this insoluble solid is the standard form of silver chloride used in reference electrodes, photographic emulsions, antimicrobial coatings, and as a precursor for other silver compounds. Its characteristic curdy white precipitate and light sensitivity (darkens to purple-gray upon exposure) make it essential for qualitative chloride detection, potentiometric titrations, and silver halide-based imaging systems. Aure Chemical provides controlled particle size, low impurity levels (especially heavy metals), and secure silver sourcing to ensure batch consistency and optimal performance in laboratory, industrial, and high-tech applications worldwide.
