Description
POTASSIUM SULFATE (K2O4S) is an inorganic compound with an average molecular weight of 174.26 g/mol. POTASSIUM SULFATE belongs to the alkali metal sulfates, a subclass of alkali metal oxoanionic compounds within the inorganic compounds. It is classified as a mixed metal/non-metal compound. Industrially, the compound is utilized as a fertilizer (PMC8034859). Its other industrial roles include use as a viscosity modifier, a nutrient and flavouring, a processing aid not otherwise specified, and as a nucleating agent for crystal growth modifiers (PMC8034859). Regarding its biological activity, one protein target has been recorded: the sodium/potassium-transporting ATPase subunit alpha-1 (ATP1A1). POTASSIUM SULFATE is found in or released from 17 recorded sources. Within food, food processing, and cookware, it is associated with the preparation of vinegar, the preparation of wort, the preparation of wine or sparkling wine, fermentation processes for beer, and the processing of meats, among one other source. In the category of household cleaning and consumer products, it is found in tobacco smoke filters, tobacco product moisture control, cigar cigarettes, and bleaching agents. In the building and construction sector, it is linked to tents or canopies and fencing. Additionally, it is released from electrical and electronic equipment, specifically magnets, fixed capacitors and their manufacture, electrically stimulated smoking devices, electric switches, and communication cables or conductors.
