Volatile Thiols

Abstract Generally, volatile thiols are hard to be measured with ESI (electrospray ionization)-type LC-MS due to the volatility. Therefore, we here evaluated the pretreatment of their S-bimanyl derivatization by monobromobimane to enable the detection as nonvolatile derivative. Consequently, we successfully developed the convenient and efficient method through the quantitative analysis of 2-furanmethanethiol (volatile thiol odorant of coffee aroma) in coffee bean.
