Given the profound long\u2010term impact of maternal diet on offspring, its safety during pregnancy is of particular concern. Existing detection methods primarily target food matrices and lack reliable, efficient approaches for biological sample analysis. To address this gap, we developed an ultrahigh\u2010performance liquid chromatography\u2013multiple reaction monitoring tandem mass spectrometry (UHPLC\u2013MS\/MS) method based on existing food detection methods to quantify sucralose in mouse serum and placenta. Method validation showed excellent linearity in the range of 20\u20131250\u2009nmol\/L, with limit of detection (LOD) of 4.88\u2009nmol\/L and limit of quantification (LOQ) of 9.77\u2009nmol\/L. The precision, accuracy, matrix effects, and freeze\u2013thaw stability were all within acceptable limits. Using the method described above, we detected sucralose in both serum and placenta of mice following subchronic exposure, confirming its bioaccumulation, systemic absorption, and transplacental transfer, suggesting the need for further reproductive toxicity studies. In summary, this study developed and preliminarily applied a method for determining sucralose in mouse serum and placenta, providing a methodological reference for the toxicological evaluation and safety assessment of sucralose, and aids in improving food safety risk systems and the formulation of evidence\u2010based public health policies.<\/jats:p>","DOI":"10.1002\/bmc.70610","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T03:43:16Z","timestamp":1788234196000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development and Preliminary Application of a Method to Detect Sucralose in Placenta and Serum"],"prefix":"10.1002","volume":"40","author":[{"given":"Ying","family":"He","sequence":"first","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Yin","sequence":"additional","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Run","family":"Ling","sequence":"additional","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yidan","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6375-3590","authenticated-orcid":false,"given":"Junlin","family":"He","sequence":"additional","affiliation":[{"name":"Department of Health Toxicology, School of Public Health Chongqing Medical University  Chongqing China"},{"name":"Joint International Research Laboratory of Reproduction &amp; Development Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"423","volume-title":"Profiles of Drug Substances, Excipients and Related Methodology","author":"AlDeeb O.
