General description

S 421 belongs to the class of chloroalkyl ether compounds.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
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.

2,3,3,3,2',3',3',3'-Octachlorodipropyl ether (Abbreviation; S-421) is originally developed as synergist of a pyrethroid insecticide. In recent years, S-421 is used widely at home, for a mosquito-repellent incense, electric mosquito-repellent, an insect-killing spray, a vacuum cleaner paper pack, etc. as well. On
