Chloroform dos not have a flash point. Saying this does not mean a relax on precautions since CHCl3 bottle usually has some ethanol "as stabilizer" and ethanol is volatile & flammable.
As you know, chloroform was used as general anesthetic & then skipped. So my advice is to try another solvent for the drug such as dichloromethane "DCM" CH2Cl2. Of course, DCM will be disposed after it does its job.
