Mercury chloride

Mercury(I) chloride (CAS 10112-91-1 ), commercially known as calomel, is an inorganic mercury salt used as a reference electrode material and catalyst in specialized industrial and laboratory settings. Its electrochemical stability makes it a benchmark compound in analytical chemistry and precision measurement applications. Calomel is the active material in saturated calomel electrodes (SCE). These serve as standard reference electrodes in electrochemical analysis, pH measurement, and corrosion testing across laboratory and industrial quality control environments. In electronics manufacturing, it supports calibration processes where stable, reproducible electrode potentials are required. Pharmaceutical and chemical research facilities use it as a catalyst. It is utilized in select organic synthesis reactions where mercury-based catalysis offers specific selectivity advantages. Historically significant in pharmaceutical compounding, it remains a reference compound. It is used in regulatory and analytical standards work. Mercury(I) chloride is supplied as a white to off-white crystalline powder available in reagent-grade and analytical-grade specifications. These grades meet laboratory and industrial purity requirements. Packaging is typically offered in small quantities consistent with its specialized, low-volume demand profile.
