FAQS on citric acid anhydrous specification
Q: What is citric acid anhydrous specification?
A: Citric acid anhydrous specification refers to its purity, moisture content (≤0.5%), and compliance with standards like USP/FCC. It must have a CAS number of 77-92-9 and pH between 1.7-2.2 in solution. Specifications ensure suitability for food, pharmaceutical, and industrial uses.
Q: What is the difference between anhydrous citric acid and citric acid monohydrate?
A: Anhydrous citric acid contains no water molecules, while monohydrate has one water molecule per citric acid molecule. The anhydrous form is drier (0.5% max moisture) and preferred in moisture-sensitive applications. Monohydrate loses water above 74°C, converting to anhydrous.
Q: How does anhydrous citric acid vs citric acid affect shelf life?
A: Anhydrous citric acid has longer shelf life due to lower moisture content, reducing clumping and microbial growth. Monohydrate may absorb moisture over time, requiring stricter storage conditions. Both remain stable if kept in sealed containers below 25°C.
Q: Why choose anhydrous citric acid over monohydrate in pharmaceuticals?
A: Anhydrous citric acid is preferred for dry formulations like tablets where moisture control is critical. It ensures precise dosing without water interference. Monohydrate is used in liquid preparations where water content isn't problematic.
Q: How to verify citric acid anhydrous meets specification?
A: Test using pharmacopeial methods: Karl Fischer titration for moisture (≤0.5%), FTIR for identification, and titration for assay (99.5-100.5%). Certificates of Analysis from suppliers should confirm compliance with USP/FCC/EP standards.
Q: Does citric acid anhydrous specification impact solubility?
A: No, both forms have identical solubility (592g/L at 20°C) once dissolved. The anhydrous form simply requires slightly less mass to achieve equivalent acidity. Solubility differences only exist in solid-state crystal structures.
Q: Can anhydrous citric acid and monohydrate be used interchangeably?
A: Yes, but with formula adjustments: 1g monohydrate ≈ 0.914g anhydrous. Anhydrous is better for dry mixes or low-moisture products. Monohydrate may require additional drying steps in hygroscopic applications.
