Description

General description

S 421 belongs to the class of chloroalkyl ether compounds.

Application

S 421 may be used as an analytical reference standard for the determination of S 421 in:

• Tobacco samples by citrate QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction in acetonitrile solvent, low-temperature precipitation (LTP) and dispersive solid phase extraction (d-SPE) followed by analysis using gas chromatography combined with tandem mass spectrometry (GC-MS/MS) with electron impact (EI) ionization and selected reaction monitoring (SRM) detection.
• Fresh tea shoots, tea infusion and spent tea leaves by GC coupled with ⁶³Ni electron capture detector (ECD) and GC-MS operating on EI mode of detection.
• Indoor air samples by GC-EI-MS equipped with selected ion monitoring (SIM) detection.[1]
