The mostÌýwell-knownÌýuse 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 andÌýsulphonicÌýacids.
B-MercaptoethanolÌýis an antioxidant.
Recommended control measures​
Minimise the risk of exposure
- Always assess where the work is going to happen, thiols usually have high volatility so vapour will be produced.​
- Do not work directly in a fume cupboard without filtration, either on the fume cupboard or on theÌýexperiment, as theÌýsmell will just be transported rather than removed.​

Due to the volatility, store in a manner that will expect vapour to be produced and controlledÌý​
Use
- Always inform the people working in the area and the department that works with thiols is to goÌýahead, in case of accident release.​
- When possible ensure that all thiol vapour is caught and re-oxidised at the source. ​
Health surveillanceÌý​
None.
