The most听well-known听use for thiols is as the odour in natural gas, they feature heavily in research due to their biological importance and thiols can be used to make disulphides and听sulphonic听acids.
B-Mercaptoethanol听is an antioxidant.
Recommended control measures鈥�
Minimise the risk of exposure
- Always assess where the work is going to happen, thiols usually have high volatility so vapour will be produced.鈥�
- Do not work directly in a fume cupboard without filtration, either on the fume cupboard or on the听experiment, as the听smell will just be transported rather than removed.鈥�

Due to the volatility, store in a manner that will expect vapour to be produced and controlled听鈥�
Use
- Always inform the people working in the area and the department that works with thiols is to go听ahead, in case of accident release.鈥�
- When possible ensure that all thiol vapour is caught and re-oxidised at the source. 鈥�
Health surveillance听鈥�
None.
