[PharmSciTech]Re: Residual solvents

["Brian MATTHEWS" <LT09@dial.pipex.com>]

Bob,

Spot on!

One special issue to look out for:  toluene is sometimes used in the 
manufacture of excipients or APIs.  The toluene often contains trace 
quantities of benzene so that controls for residues of benzene (= 
class I) may be required.

Regards,

Brian Matthews.
