L-ascorbic acid phosphate magnesium salt(CAS: 108910-78-7)

L-ascorbic acid phosphate magnesium salt is a crystalline solid with a molecular weight of approximately 389.33 g/mol. It is slightly soluble in water and is more stable in aqueous solutions than its parent compound. This salt is less reactive than free L-ascorbic acid and shows good thermal stability, making it suitable for various applications in the food and pharmaceutical industries.

L-ascorbic acid phosphate magnesium salt is typically synthesized by reacting L-ascorbic acid with magnesium phosphate. Common methods involve the use of magnesium phosphate and L-ascorbic acid in a suitable solvent, followed by filtration and drying to obtain the salt. The reaction is carried out under mild conditions to ensure selectivity and yield, with magnesium phosphate serving as the key catalyst.

L-ascorbic acid phosphate magnesium salt finds applications in the pharmaceutical industry, primarily as a vitamin C precursor and antioxidant. It is also used in the food industry as a preservative and to enhance the stability of vitamin C in food products. Additionally, it has applications in the cosmetic industry, where it is used as a skin care ingredient due to its antioxidant properties.

When handling L-ascorbic acid phosphate magnesium salt, it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Work should be conducted in a well-ventilated area or fume hood to prevent inhalation of dust. In the event of a spill, immediately clean it up using appropriate absorbent materials and dispose of waste according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling and safety information.
