An efficient and general synthetic route of deuterium-labeled phthalate esters is described with high isotopic enrichment and excellent chemical purities using inexpensive and readily available o-xylene-D10 as labeled starting material. The structures and isotope-abundance were confirmed via 1H NMR and mass spectrometry. These deuterium labeled phthalate esters can be used as analytical reference standards for the detection of plasticizer residues in soil, water, food, plastic products, etc.
本文介绍了一种高效且通用的合成氘标记邻苯二甲酸酯的方法,该方法使用廉价且易得的氘标记o-二甲苯作为起始材料,实现了高同位素富集度和优异的化学纯度。通过1H NMR和质谱法确认了其结构和同位素丰度。这些氘标记邻苯二甲酸酯可作为分析参考标准,用于检测土壤、水、食品、塑料制品等中的增塑剂残留。
