Silver Nitrate CAS 7761-88-8

High-Purity Silver Nitrate from Aure Chemical – Your Trusted Source

Silver nitrate, AgNO₃, CAS No. 7761-88-8, is the most important and versatile silver(I) precursor used across industries. Supplied by Aure Chemical as colorless to white crystalline powder or granules with high silver content (typically 63–64% Ag), this highly soluble compound serves as an efficient source of Ag⁺ ions for a wide range of applications. It is the primary precursor for silver nanoparticle synthesis, silver electroplating baths, photographic emulsions, antimicrobial coatings, catalysis, and organometallic silver complex preparation. Its strong oxidizing properties and reactivity with halides make it indispensable in qualitative analysis, mirror production, and as a reagent in organic synthesis. Aure Chemical provides precise Ag assay, low impurity levels (especially chloride and heavy metals), and secure silver sourcing to ensure batch consistency and optimal performance in laboratory, industrial, and high-tech applications worldwide.

Primary Applications of Silver Nitrate

Silver Nitrate is the workhorse silver precursor for reduction, deposition, and analytical applications across multiple industries.

1. Silver Nanoparticle & Colloid Synthesis
   Serves as the primary silver source for controlled reduction to monodisperse Ag nanoparticles using citrate, borohydride, or polyol methods — essential for antimicrobial coatings, SERS substrates, biosensors, and plasmonics.

2. Silver Electroplating & Electroless Deposition
   Provides Ag⁺ ions for electrolytic and autocatalytic silver plating baths, producing bright, highly conductive coatings on electronics, mirrors, and decorative items.

3. Supported Silver Catalyst Preparation
   Used in impregnation or deposition to create Ag on carbon, alumina, or oxide supports for selective oxidation, ethylene oxide production, and formaldehyde synthesis.

4. Photography & Imaging
   Classic precursor for preparing light-sensitive silver halide emulsions in traditional photography and radiographic films.

5. Antimicrobial & Medical Applications
   Employed in formulation of silver-based antiseptics, wound dressings, and medical device coatings due to its strong antimicrobial activity.

6. Analytical Chemistry & Staining
   Widely used as a reagent for chloride detection, protein staining, and qualitative analysis in laboratories.
