Ascorbic Acid Extra Pure, commonly known as Vitamin C, is a high-purity, white to slightly yellow crystalline powder widely used in laboratory settings for analytical, biochemical, and pharmaceutical research. It functions as a potent reducing agent and antioxidant, making it valuable in redox titrations, radical scavenging assays, and studies of oxidative stress and enzyme activity. Ascorbic acid is also used in food chemistry experiments and as a stabilizer in formulations prone to oxidation. The extra pure grade ensures minimal contaminants, supporting precise and reproducible results in sensitive applications. It should be stored in tightly sealed containers, protected from light, heat, and moisture to preserve its stability and effectiveness.
