FAQ
Is this suitable for HPLC standards?
Yes, high purity allows use as a reference standard in chromatography.
Can it be dissolved in ethanol?
Solubility is low; water or buffer solutions are preferred.
Why does it turn yellow?
Oxidation occurs with air and light exposure—store properly.
How to verify purity?
Use titrimetric or UV-Vis methods at 243 nm.
Can it be autoclaved?
No, heat degrades ascorbic acid—filter sterilize instead.
