Understanding the fundamental science behind Citric Acid Monohydrate (CAS 5949-29-1) is key to appreciating its widespread utility. NINGBO INNO PHARMCHEM CO.,LTD. provides a premium grade of this organic acid, backed by insights into its chemical characteristics and how it is produced commercially.

Citric Acid Monohydrate is the crystalline form of citric acid that incorporates one molecule of water within its structure (C₆H₈O₇·H₂O). It typically appears as a white, crystalline powder with a distinctively sour taste and is odorless. Compared to its anhydrous counterpart, the monohydrate form offers greater stability in humid conditions, making it a preferred choice for many applications where moisture management is a consideration.

Commercially, Citric Acid Monohydrate is predominantly produced through microbial fermentation. This process typically involves the use of carbohydrates, such as sucrose or glucose, which are fermented by specific strains of the fungus *Aspergillus niger*. This biotechnological approach is highly efficient and allows for large-scale production while maintaining high purity levels. The fermentation broth is then subjected to a series of purification steps, including filtration, neutralization (often with calcium hydroxide to form calcium citrate), and subsequent acidification and crystallization to yield the final Citric Acid Monohydrate product. Manufacturers looking to buy citric acid monohydrate often prioritize products from such well-controlled fermentation processes.

The chemical properties of Citric Acid Monohydrate, including its acidity (pKa values are approximately 3.13, 4.76, and 6.40), its ability to chelate metal ions, and its role as a pH buffer, are directly related to its molecular structure. These properties dictate its wide-ranging uses of citric acid monohydrate across various industries, from food and beverage to pharmaceuticals and industrial cleaning.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Citric Acid Monohydrate adheres to strict quality standards, reflecting the meticulous manufacturing processes required to produce this vital ingredient. Understanding these scientific underpinnings further solidifies its position as an indispensable chemical compound in modern industry.
