Phosphoric acid (CED0000848)

Phosphoric acid (H3O4P) is an endogenous solid with an average molecular weight of 98.00 g/mol. Phosphoric acid belongs to the non-metal phosphates, a subclass of non-metal oxoanionic compounds within the inorganic compounds. This compound targets the estrogen receptor beta (ESR2) and is used in the production of polyamide plastics. In industrial applications, phosphoric acid serves as an acid (PMC11467972, PMC7344730, PMC9088909, PMC9925910) and a catalyst (PMC11587018). Its diverse industrial roles include use as a stabilizing agent, bleaching agent, pH regulating agent, flux agent, flavouring and nutrient, dispersing agent, conductive agent, and etching agent. Additionally, it is employed as a corrosion inhibitor, degradant/impurity, cleaning agent, oxidizing agent, biocide, chelating agent, wetting agent (non-aqueous), and for soil amendments. Phosphoric acid is found in or released from 67 recorded sources. These include electrical and electronic equipment such as antennas, amplifiers, coils, adjustable resistors, and auxiliary devices. It is present in household cleaning and consumer products, including match receptacles or boxes, bleaching agents, cigar cigarettes, other smoking requisites, and non electric simulated smoking devices. Within food, food processing, and cookware, it is associated with food preservation, the preparation of malt, fermentation processes for beer, molasses and the treatment of molasses, and agglomerated sugar products. It is also found in building and construction materials such as floors, ceilings, roofs, fencing, and ladders.
