FAQs
1. What is the solubility of aesculin sesquihydrate in common lab solvents?
Aesculin sesquihydrate is freely soluble in water and ethanol, with moderate solubility in methanol. It is sparingly soluble in non-polar solvents like chloroform.
2. Can this product be used for fluorescence-based detection methods?
Yes, aesculin sesquihydrate exhibits strong blue fluorescence under UV light (365 nm), making it suitable for fluorescence-based assays and detection protocols.
3. How should aesculin sesquihydrate be stored for long-term stability?
Store in a tightly sealed container at room temperature (15–25°C), protected from light and moisture. Avoid exposure to direct sunlight or high humidity to prevent degradation.
4. Is this grade compatible with microbial culture media?
Yes, the extra pure grade is ideal for incorporation into agar or broth media, particularly for selective isolation or differentiation of microorganisms like *Enterococcus* species.
5. What alternatives exist if aesculin sesquihydrate is unavailable?
Esculin (anhydrous form) can be used as an alternative, though adjustments to concentration may be needed due to differences in molecular weight and hydration state.
