一般描述
2-Ethylhexanoic acid is one of thedi(2-ethylhexyl)phthalate (DEHP) metabolites.
应用
2-Ethylhexanoic acid has been used as a reference standard for the determination of 2-ethylhexanoic acid in human urine by gas chromatography?mass spectrometry (GC-MS) in selected ion monitoring (SIM) mode. It may be used as a reference standard for the analysis of 2-ethylhexanoic acid in grape musts and skins as aroma compounds released by fast acid hydrolysis of flavor precursors by GC-MS technique and in Thai soy sauce by dynamic headspace (DHS) sampling, direct solvent extraction (DSE) and vacuum simultaneous steam distillation?solvent extraction (V?SDE) combined with GC-MS.
其他说明
Ion Mobility:TWCCSN2value of 136.0 ?2 [M-H]-
The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.
TWCCS measurements are expected to be within 2% of this reference value.
