City Chemical LLC manufactures Silver Sulfate (Ag2SO4, CAS 10294-26-5) to ACS reagent grade, an off-white powder assaying at 99.9% with iron, nitrate, and insoluble matter each held below 0.02%. Because it introduces silver ion without the chloride that comes with silver nitrate in certain applications, it is a standard choice wherever an analytical method or synthesis step needs a chloride-free silver source. Every lot is supplied with a Certificate of Analysis, so analytical labs can qualify incoming material against their own method requirements.
City Chemical LLC is a privately-held, woman-owned chemical manufacturer headquartered in West Haven, Connecticut. Backed by more than a century of combined operating history, we specialize in rare, unusual, and hard-to-find chemicals that are difficult to source elsewhere. Every order is backed by our ResponseAbilityTM commitment — a dedication to speed, accuracy, and responsiveness at every stage of the chemical purchasing process. Whether you need a small lab-scale quantity or a large industrial order, our team works to deliver the exact specification, packaging, and turnaround your project requires.

Common Uses & Applications: analytical chemistry reagent, including use as a chloride-free source of silver ion in titrations and precipitation reactions, a catalyst in chemical oxygen demand (COD) water testing and Kjeldahl nitrogen digestion, and a starting material in electroplating and other silver salt manufacturing.
Silver Sulfate for Analytical and Industrial Use
Silver sulfate’s main practical advantage is what it does not bring to a reaction: unlike silver nitrate, it introduces no nitrate ion and no chloride, which matters in methods where either would interfere. That property is why it shows up as a specified reagent in water-testing methods like COD and in Kjeldahl digestion, and why synthesis chemists reach for it when they need silver ion delivered cleanly into a system that cannot tolerate the counter-ion that comes with other silver salts.
As a Silver Sulfate manufacturer, City Chemical LLC supplies analytical laboratories, electroplating operations, and specialty chemical manufacturers who need a documented ACS-grade reagent rather than a nominal one. A Certificate of Analysis accompanies every lot, confirming assay and the trace-impurity limits that analytical work depends on.
