As weighing anthocyanin standard (keracyanin chloride; ACN STD) is very difficult and risky, the plan is to dissolve ACN STD with analytical solvent which is not soluble with water or alcohol (Information source: https://www.scbt.com/p/keracyanin-chloride-18719-76-1#:~:text=In%20other%20studies%2C%20Keracyanin%20chloride,through%20inhibition%20of%20α-glucosidase.&text=Solubility%20%3A,Soluble%20in%20water%2C%20and%20alcohol.); thus, what solvent is suitable for dissolving ACN STD without contaminating it?

After that, the desiccant is used to dry analytical solvent; thus, what desiccant is suitable without contaminating ACN STD?

Link of research papers or video from official source will be helpful, but it's optional.

This question is related to 'How to transfer ACN STD correctly?' previously, and a video demo can be watched for better understanding.

Thank you.
