Dibenzyl Phthalate-d4 | CAS 1015854-62-2

OVERVIEW  of  Dibenzyl Phthalate-d4 

Dibenzyl Phthalate-d₄ is a deuterium-labeled phthalate ester used primarily as an internal standard for mass spectrometric analysis of dibenzyl phthalate in environmental, industrial, and consumer product testing. The incorporation of four deuterium atoms in the aromatic ring provides a clear mass shift, enabling highly accurate isotope-dilution quantification.
