FAQS on citric acid cas no 77 92 9
Q: What is the CAS number for citric acid?
A: The CAS number for citric acid is 77-92-9. This unique identifier is used globally to specify the chemical compound. It applies to citric acid in both anhydrous and monohydrate forms.
Q: What is the difference between citric acid anhydrous and citric acid monohydrate?
A: Citric acid anhydrous contains no water molecules, while citric acid monohydrate has one water molecule per citric acid molecule. The monohydrate form is less concentrated due to the added water. Storage conditions may vary based on moisture sensitivity.
Q: Which is more stable: citric acid anhydrous or citric acid monohydrate?
A: Citric acid anhydrous is more stable in dry environments, whereas citric acid monohydrate is prone to clumping in humid conditions. Stability depends on storage temperature and moisture levels. Anhydrous is often preferred for long-term storage in pharmaceuticals.
Q: Can citric acid anhydrous and citric acid monohydrate be used interchangeably?
A: They can often be substituted, but adjustments are needed for the water content in formulations. Monohydrate adds slight moisture, which may affect recipes or industrial processes. Always verify purity and compatibility for specific applications.
Q: How does the molecular formula differ between citric acid anhydrous and monohydrate?
A: Both forms share the base formula C6H8O7, but the monohydrate includes an additional H2O molecule (C6H8O7·H2O). This structural difference affects solubility and weight calculations. Applications may vary based on these properties.
