Product Details
Products Description of Citric acid monohydrate CAS#5949-29-1
Industrial-grade citric acid monohydrate (also referred to as monohydrate citric acid) boasts a minimum purity of 99.5%, presenting as an odorless, combustible white crystalline powder. Its key physicochemical properties are as follows: the melting point ranges from 135℃ to 152℃, with a boiling point of 309.6℃; vapor pressure is less than 1Pa at 25℃, and relative density is 1.54 (20℃). The compound exhibits high solubility in water (1630g/L at 20℃), is miscible with ethanol, and has slight solubility in ether. It maintains good chemical stability under standard conditions but is incompatible with strong oxidizing agents.

Product Application of Citric acid monohydrate CAS#5949-29-1
Citric Acid Monohydrate is a naturally occurring tricarboxylic acid sourced from citrus fruits, and it serves as a versatile excipient in pharmaceutical formulations by virtue of its inherent antioxidant activity. Its core functions in drug preparations include: preserving the chemical stability of active pharmaceutical ingredients (APIs) to extend shelf life, acting as a preservative to inhibit microbial growth, regulating formulation pH as a reliable acidulant, and exerting anticoagulant effects via calcium ion chelation in blood—making it suitable for specific clinical and diagnostic applications.
