Dimethyl phthalate can widely find applications in industries, for the manufacture of polyvinyl chloride and cellulose ester-based plastics like cellulose acetate and cellulose butyrate.

Application

Dimethyl phthalate may be used as an analytical standard for the determination of the analyte in food products, vegetables, cosmetic and environmental samples by gas chromatography technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Other Notes

Ion Mobility: TWCCSN2 value of 134.1 Å2 [M+H]+ and 146.1 Å2 [M+Na]+

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.
