Description

2,3,4,5,6-Pentahydroxyhexanoic Acid is a polyhydroxy carboxylic acid derivative, also known as D-Gluconic Acid, which serves as a versatile intermediate and functional ingredient. Its value lies in its chelating, mild acidity, and metal-sequestering properties, making it a key component in formulations requiring controlled pH and stabilization. This compound is essential for manufacturers in the food, pharmaceutical, personal care, and industrial cleaning sectors seeking effective and safe organic acids.

Application

• Food & Beverage Industry: Used as a pH regulator, sequestrant, and leavening agent in baked goods and beverages.
• Pharmaceutical Synthesis: Serves as a chiral building block and an excipient in tablet formulations and calcium supplements.
• Personal Care & Cosmetics: Acts as a gentle chelating agent and pH adjuster in skin cleansers, shampoos, and oral care products.
• Industrial Cleaning & Descaling: An effective component in alkaline and acid detergent formulations for removing mineral deposits without corrosion.
• Agriculture & Animal Feed: Utilized as a feed additive and in certain agrochemical formulations for its chelating action.
• Concrete & Construction: Employed as a set retarder and water reducer in concrete admixtures.
• Textile & Leather Processing: Functions as a sequestrant in dyeing processes and leather tanning to improve quality.
• Metal Surface Treatment: Used in electroplating and metal cleaning baths for its metal-complexing properties.

Quality Control

Our 2,3,4,5,6-Pentahydroxyhexanoic Acid is produced and tested under a stringent quality management system. We offer grades compliant with relevant standards such as FCC (Food Chemicals Codex) and USP (United States Pharmacopeia) where applicable. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation.
