Assay of diethylhexyl terephthalate (DEHTP) – CAS No. 6422-86-2

Diethylhexyl terephthalate (DEHTP) is an alternative plasticizer to conventional phthalates, used in the manufacture of flexible plastics, films, cables, food packaging or consumer products.

The measurement of diethylhexyl terephthalate (DEHTP) is essential for verifying compliance with technical specifications, monitoring migration levels in food contact materials, and ensuring the traceability of raw materials in sensitive production chains. Analysis is generally performed by gas chromatography-mass spectrometry (GC-MS) after targeted extraction. This method allows for precise quantification, even at trace levels, in plastic matrices, polymers, coatings, or liquids.

At YesWeLab , we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
If you have any particular requirements, please do not hesitate to specify them in your request: our scientific team will do everything possible to respond accurately and promptly.
Since 2020, numerous manufacturers, distributors, and engineering firms have entrusted us with the management of their analyses, sending us their samples through our digital platform.
