When sourcing Ascorbic Acid, commonly known as Vitamin C, understanding its quality specifications is paramount to ensure it meets the intended application requirements, whether for pharmaceutical, food, or feed use. These specifications guarantee the purity, efficacy, and safety of the product.

A key specification is the Assay, which indicates the purity of the Ascorbic Acid. Typically, pharmaceutical and food grades will have an assay of 99.0% to 105.0%, ensuring a high concentration of the active compound. Identification tests, such as positive reactions to specific tests, confirm that the substance is indeed Ascorbic Acid.

Impurities and their limits are also critical. Specifications like Loss on drying (not exceeding 0.25%) and Residue on ignition (less than 0.1%) are important indicators of the product's purity and the absence of volatile matter or inorganic impurities. Limits on Heavy metals (less than 10ppm) and Arsenic (less than 3ppm) are vital for safety, especially in food and pharmaceutical applications.

The Grade of Ascorbic Acid, such as Medicine Grade, Food Grade, or Feed Grade, dictates its suitability for different industries. Adherence to standards like BP 2000 or USP 32 is crucial for pharmaceutical applications, ensuring compliance with regulatory requirements. The physical form, described as Appearance (White or almost white granule or granular powder), and Mesh size distribution, are also important for handling and formulation.

For manufacturers and consumers alike, ensuring that Ascorbic Acid Vitamin C Powder meets these stringent specifications is essential. This commitment to quality guarantees that the product will perform as expected and remain safe for its intended use, providing confidence in its efficacy as a Nutritional Enhancer and antioxidant.
