Descripción

General description

tert-Butanol is a tertiary alcohol and an isomer of butanol. It is commercially produced from isobutane and is used as a solvent, ethanol denaturant, etc.

Application

The analytical standard can also be used as follows:

• Detection and quantification of butanol and its isomers in paint samples by a rapid fast gas chromatography-proton transfer reaction-mass spectrometer (FastGC-PTR-MS) method
• Simultaneous assessment of 121 VOCs emitted from 41 cellulose acetate movie films by proton transfer reaction-time-of-flight-mass spectrometry (PTR-ToF-MS)
• As an internal standard in the determination of n-butane and its metabolites in the blood, heart, and tissue samples of three autopsy cases that died due to sniffling n-butane and isobutane from portable gas cartridges
• Headspace-single drop microextraction (HS-SDME) of VOCs from different types of tomato samples for their quantification by gas chromatography-flame ionization detection (GC-FID)
