Description

Description générale

Tri-o-tolyl phosphate is classified under the class of non-halogenated organophosphate esters (OPEs).

Application

Tri-o-tolyl phosphate may be used as an analytical reference standard for the determination of tri-o-tolyl phosphate in:

• Analysis of tri-o-tolyl phosphate in edible oils by TLC and GC is described in methods FSSAI 02.036:2021 and FSSAI 02.037:2021
• Surface water and wastewater effluent samples by liquid chromatography coupled to tandem mass spectrometry equipped with electrospray ionization (LC-ESI-MS/MS) operating under the multiple reaction monitoring (MRM) mode of detection.
• Human hair and nails by liquid-liquid extraction (LLE) and gas chromatography-mass spectrometry (GC-MS).
• Indoor air, dust and window wipes by GC-MS/MS.
• Outdoor air samples by ultra-performance liquid chromatography coupled to triple quadrupole mass spectrometry (UPLC-QqQ-MS/MS) equipped with ESI source and MRM detection.
