Neil, the R & S You refer to could be concerning the stereochemistry of the material in question. "R" is german for Rectus which means Right, and "S" is for Sinster which is for Left.
If this is incorrect I apologize, but this is my best guess.

Subject: [DCHAS-L] R-S Phrases

Does anyone know of a source of R-S Phrases assigned to pure chemicals?  Searching through MSDSs is tedious and with the growth of GHS a list is becoming important
