Description

Dl-Tartaric Acid Calcium Salt is the calcium salt form of the racemic mixture of tartaric acid. This compound is valued for its role as a chiral resolving agent and a source of bioavailable calcium in various formulations. It is primarily sought by manufacturers in the pharmaceutical, food, and nutraceutical industries for applications requiring calcium fortification or specific stereochemical control.

Application

• Pharmaceutical Excipient: Used as a calcium source in tablet and capsule formulations, including effervescent systems.
• Nutraceutical Ingredient: Serves as a dietary supplement for calcium enrichment in functional foods and beverages.
• Chiral Resolution Agent: Employed in the separation of racemic mixtures of organic compounds, particularly in fine chemical synthesis.
• Food Additive: Functions as a firming agent, stabilizer, or leavening acid component in certain food products.
• Laboratory Reagent: Utilized in analytical chemistry and biochemical research as a standard or buffer component.
• Chemical Intermediate: Acts as a precursor or additive in the synthesis of more complex tartrate derivatives.

Quality Control

Our Dl-Tartaric Acid Calcium Salt is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for identity, purity, and composition. A Certificate of Analysis (COA) detailing results for assay, heavy metals, loss on drying, and other relevant parameters is provided with every shipment. We can supply material compliant with in-house specifications tailored for pharmaceutical, food, or technical grade applications.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
