Description
N-(Isoxazol-5-yl)sulphanilamide is one of the inorganic compounds that is commonly used in food industry thanks to its ability of acting as a chemical buffer. It helps stabilize the PH value, prevent coagulation, and enhance food characteristics like nutritional value and cooking performance. It also finds application in medical use. It can stimulate general liver activities, allowing it to operate in the first place. Besides, disodium phosphate can be used in non-food industries. It can be applied in water treatment for retarding the formation of calcium scale. It is also found in some flame retardant, detergents and cleaning agents.Related product price
