D-(+)-Glucono-1,5-lactone (GDL) is a natural food-grade acidulant and pH regulator derived from glucose, widely used in dairy products, beverages, and pharmaceuticals for controlled acidification without direct acidity. It is also used as a sequestering agent in cleaning compounds, to prevent milkstone and beerstone deposits, as a latent acid catalyst in textile printing, and as a tofu coagulant. It hydrolyzes to gluconic acid in solution, offering gentle, gradual pH adjustment. This USP-grade chemical has a CAS number of 90-80-2, molecular formula C6H10O6, and a molecular weight of 178.14 g/mol. It is stable at ambient storage conditions, with no signal word required for hazard classification. Molekula supplies D-(+)-Glucono-1,5-lactone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
