Description

Calcium L-Arabonate is the calcium salt of L-arabonic acid, a sugar acid derivative. This compound serves as a valuable intermediate and functional ingredient in various high-value synthesis and formulation processes. It is particularly relevant for industries requiring chiral building blocks or calcium sources with specific organic counterions, such as pharmaceuticals, nutraceuticals, and specialty chemical manufacturing.

Application

• As a calcium source in the formulation of specialized nutritional supplements and fortified foods.
• As a chiral intermediate or starting material in the synthesis of complex pharmaceutical actives and fine chemicals.
• In biochemical and microbiological research as a component of specialized culture media or buffers.
• As a potential chelating agent or sequestrant in specific industrial or laboratory processes.
• For use in the development of cosmetic and personal care formulations where calcium salts provide specific functional benefits.

Quality Control

Our Calcium L-Arabonate is produced under a rigorous quality management system. Each batch is tested to ensure identity, purity, and consistency. While specific grades can be tailored, our standard quality control includes verification of assay, optical rotation, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and handling properties.
