Like prefers like so try a system such as ether. A few beaker tests with solvents such as ethyl acetate may also be helpful. Have you tried hexane (non-polar)? This is likely to be unsuccessful but you'll learn something from this.

As Mr. Alan said, it will be soluble in ethyl-, methyl acetates and also in dimethylacetamide, chloroform.

thank you all. I will try it

I want to try deuteroporphyrin on suspension cells. So do you know if these organic solvents (hexane, ethyacetate, chloroform...) are cytotoxic ?

They can be cytotoxic even their Acute toxicity is low (for example LD50 Ethyl acetate is 4100 mg/kg [Mouse])

Please, search and see the cytotoxicity of these organic solvents from researches. Article The cytotoxicity of some organic solvents

thank you for your helpful answer
