In particular, residual formaldehyde can impair downstream molecular workflows and present occupational safety risks for collection handlers. Formaldehyde modifies biological macromolecules by forming covalent crosslinks between nucleic acids and proteins and also by promoting DNA fragmentation, which lowers extraction efficiency and limits the recovery of amplifiable genetic material. To address the need for minimally invasive, rapid formaldehyde detection, we developed a coated blade spray mass spectrometry (CBS\u2010MS) workflow using on\u2010blade derivatization with 2,4 dinitrophenylhydrazine (2,4\u2010DNPH). A custom 3D\u2010printed multiblade holder enabled rapid sequential analysis of 12 blades held in identical positions. Qualitative confirmation on formalin\u2010fixed mammals established detection, while application to archival specimens of the minute fruit bat (\n                    <jats:italic>\n                      <jats:styled-content style=\"fixed-case\">Cynopterus minutus<\/jats:styled-content>\n                      )\n                    <\/jats:italic>\n                    detected formaldehyde in samples recorded only as alcohol\u2010preserved. Variation in signal intensity was observed across replicates, and paraformaldehyde was visually apparent. Overall, the CBS\u2010MS approach offers a minimally invasive, efficient strategy for characterizing preservation chemistry in fluid\u2010stored specimens.\n                  <\/jats:p>","DOI":"10.1002\/jms.70080","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T11:36:41Z","timestamp":1783597001000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Derivatization\u2010Enabled Detection of Formalin From Preserved Tissues Using Coated Blade Spray Mass Spectrometry"],"prefix":"10.1002","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1911-3571","authenticated-orcid":false,"given":"Jessie F.","family":"Deng","sequence":"first","affiliation":[{"name":"Smithsonian Museum Conservation Institute  Suitland Maryland USA"},{"name":"Department of Chemistry Queen's University  Kingston Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2412-4003","authenticated-orcid":false,"given":"Arlo","family":"Hinckley","sequence":"additional","affiliation":[{"name":"Department of Vertebrate Zoology Smithsonian National Museum of Natural History  Washington, District of Columbia USA"},{"name":"Departamento de Zoolog\u00eda Universidad de Sevilla  Sevilla Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary Faith","family":"Flores","sequence":"additional","affiliation":[{"name":"Department of Vertebrate Zoology Smithsonian National Museum of Natural History  Washington, District of Columbia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Viera","sequence":"additional","affiliation":[{"name":"Department of Vertebrate Zoology Smithsonian National Museum of Natural History  Washington, District of Columbia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2783-7532","authenticated-orcid":false,"given":"Richard D.","family":"Oleschuk","sequence":"additional","affiliation":[{"name":"Department of Chemistry Queen's University  Kingston Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8929-1593","authenticated-orcid":false,"given":"Melissa T.
