Dibenzyl phthalate-3,4,5,6-d4 (CAS 1015854-62-2)

Dibenzyl phthalate-3,4,5,6-d4 is an isotopically labeled analogue of dibenzyl phthalate, a phthalate ester compound. In this labeled version, deuterium atoms replace hydrogen atoms at specific positions, which is useful in various research applications. This labeling is particularly beneficial for environmental studies where Dibenzyl phthalate-3,4,5,6-d4 serves as an internal standard in the accurate quantification of dibenzyl phthalate in environmental samples using techniques like gas chromatography-mass spectrometry (GC-MS). It aids in distinguishing between the labeled compound and potential interferences from the sample matrix or similar compounds. Furthermore, this labeled compound enables researchers to track the environmental degradation and metabolic fate of dibenzyl phthalate, as the deuterium label is not affected by the same processes that may alter the concentration of the non-labeled compound. The use of Dibenzyl phthalate-3,4,5,6-d4 is also significant in the calibration of analytical instruments to ensure the reliability and reproducibility of the data obtained during the analysis of phthalate esters, which are ubiquitous environmental contaminants due to their widespread use as plasticizers.
