Does anyone know where to find the studies/source data for LD50 values listed in SDSs? I'm specifically looking for studies/data on the reproductive/developmental hazards of methylene chloride and N-methyl-2-pyrrolidone (CAS # 872-50-4). Is there a database somewhere or does each manufacturer keep its source data in-house?

Thanks!
