D-(+)-Glucono-1,5-lactone is a naturally derived lactone used as a slow-release acidifier, pH adjuster, and preservative in food, pharmaceuticals, and cosmetics. It also serves as a sequestering agent in cleaning compounds, preventing milkstone and beerstone deposits, as a latent acid catalyst in textile printing, and as a tofu coagulant. It hydrolyzes to gluconic acid, gently lowering pH without harshness. Catalogue details: CAS 90-80-2, molecular formula C6H10O6, molecular weight 178.14, stable at ambient storage, no signal word required. Molekula supplies D-(+)-Glucono-1,5-lactone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
