Adipic Acid USP
Adipic acid or hexanedioic acid is the organic compound with the formula C6H10O4 .From an industrial perspective, it is the most important dicarboxylic acid. It occurs as white crystalline powder.
Small but significant amounts of adipic acid are used as a food ingredient as a flavorant and gelling aid. It is used in some calcium carbonate antacids to make them tart. As an acidulant in baking powders, it avoids the undesirable hygroscopic properties of tartaric acid.
