Citric acid, with the chemical formula C6H8O7 and CAS number 77-92-9, is a foundational organic acid extensively used across various industries. Its anhydrous form, a white crystalline powder, is particularly sought after for its stability and efficacy. As a leading chemical manufacturer and supplier, we offer high-purity anhydrous citric acid, understanding its critical role in product formulation and performance.

The chemical profile of citric acid is characterized by its three carboxyl groups and one hydroxyl group, classifying it as a weak organic acid. This structure grants it excellent chelating and buffering capabilities, making it invaluable in applications requiring pH control or the binding of metal ions. Its pKa values (3.13, 4.76, and 6.39) highlight its effectiveness as a buffer in the pH range of 3 to 7, crucial for many chemical and biological processes. These properties are fundamental to its use as an acidulant in food, a pH adjuster in cosmetics, and a cleaning agent in industrial settings.

The versatility of anhydrous citric acid is evident in its broad range of applications. In the food industry, it's a preferred acidulant and preservative, enhancing flavors and extending shelf life. For manufacturers aiming to buy this ingredient, understanding its functional properties is key to optimizing recipes. Its use in pharmaceuticals ranges from being an excipient to a component in effervescent tablets, where its reactivity is harnessed for effervescence.

In industrial contexts, anhydrous citric acid is a powerful chelating agent, essential for applications like water treatment, metal cleaning, and detergent formulations. Its ability to sequester metal ions prevents them from interfering with processes or causing undesirable effects.
