Description

Calcium (R)-2-Hydroxypropionate is the calcium salt of the (R)-enantiomer of lactic acid, a high-purity chiral compound. This specific stereochemistry is critical for applications requiring precise biological activity or material properties, offering superior performance over racemic mixtures. It serves as a valuable intermediate and functional ingredient for the pharmaceutical, food, and advanced materials industries, where enantiomeric purity directly impacts efficacy and product quality.

Application

• Pharmaceutical Intermediate: Used in the synthesis of chiral active pharmaceutical ingredients (APIs), particularly in drugs where the (R)-enantiomer is the therapeutically active form.
• Food & Beverage Additive: Functions as a pH regulator, preservative, or mineral source in specialized nutritional and functional food products.
• Biodegradable Polymers: A key monomer or additive in the production of polylactic acid (PLA) and other bioplastics, influencing polymer crystallinity and degradation rates.
• Animal Nutrition: Incorporated into feed as a calcium supplement and acidifier to promote gut health and nutrient absorption in livestock.
• Cosmetics & Personal Care: Acts as a buffering agent, humectant, or exfoliant in skin care formulations, valued for its natural origin and mild properties.
• Chemical Synthesis: Serves as a chiral building block or catalyst in asymmetric synthesis for fine chemicals and agrochemicals.

Quality Control

Our Calcium (R)-2-Hydroxypropionate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards, with a focus on chiral purity (enantiomeric excess), assay, and impurity profiles. Certificates of Analysis (COA) detailing specifications such as assay by titration, heavy metals content, and optical rotation are provided with every shipment. We can supply material compliant with relevant standards including Food Chemical Codex (FCC) and pharmaceutical-grade specifications upon request.

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). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from incompatible materials such as strong acids and oxidizing agents.
