Lacquer Thinner Question

Hi, all. I need some help in getting a solvent like my lacquer thinner used to be. I use it in a lab and for other cleaning operations, never for paint. We always specified "virgin lacquer thinner" and it was perfect for our apps. Last year, they started shipping thinner with a horrible odor not unlike oxygenated gas. It makes us all sick to smell. We were told to specify "virgin". That worked for a while now we can't find anything without the new additives. Please HELP? Anything similar that we can use?
