R and S numbers
« on: 10/02/2008 22:37:29 »
Hi,

Does anyone know if there is anyway to find R and S numbers online? One where you can actually find the values for spacific chemicals.

Thanks.

What sort of R and S numbers?
Do you mean R and S numbers in the sense of the safety codes used to indicate chemical hazards? Or something else, perhaps related to (R) and (S) enantiomers of a chiral molecule?

Hey,

Thanks for the reply. I mean the R and S numbers as in risk and safety. The ones you would put on a COSHH form.

Thanks.

I usually look them up in the catalogue of the chemical supplier I'm buying from (Fisher, Alfa, etc.) but if they're not there I'll also search for "MSDS [chemical name]" to check for any that are available online.
Not all chemicals have them, and to be honest I don't know how they're assigned, not all sources give the same risk phrases (risk numbers) for all chemicals. Just because they're numbers doesn't necessarily mean they're definitive...
