Description

D-Glucono-1,5-Lactone (CAS NO 1335-57-5) is a versatile organic compound belonging to the class of gluconic acid derivatives. It serves as a key intermediate and functional ingredient valued for its mild acidity and controlled hydrolysis properties. This product is essential for manufacturers in the food, pharmaceutical, and chemical synthesis industries seeking a reliable and consistent acidulant or chelating agent.

Application

• Food Industry: Used as a slow-acting acidulant in baked goods, dairy products (e.g., tofu, cheese), and meat processing to control pH and texture development.
• Pharmaceuticals: Employed as an excipient in effervescent tablets and powders where controlled acid release is required.
• Personal Care & Cosmetics: Functions as a pH adjuster and mild chelating agent in formulations like facial cleansers and shampoos.
• Industrial Cleaning: Acts as a component in descaling and metal cleaning solutions due to its ability to sequester calcium and other metal ions.
• Chemical Synthesis: Serves as a chiral building block and precursor in the synthesis of various fine chemicals and specialty materials.
• Agriculture: Utilized in certain fertilizer and animal feed additives as a source of organic acids.
