Therefore, the detection and identification of these carbamates are essential for the verification of CWC\u2010related chemicals. In this work, a series of ten carbamates (\n                    <jats:bold>1<\/jats:bold>\n                    \u2013\n                    <jats:bold>10<\/jats:bold>\n                    ) were comprehensively characterized by GC\u2010EI\/MS, GC\u2010CI\/MS, and CI\u2010MS\/MS. In addition, retention indices (RIs) were calculated based on the GC\/EI\u2010MS data for all carbamates (\n                    <jats:bold>1<\/jats:bold>\n                    \u2013\n                    <jats:bold>10<\/jats:bold>\n                    ) and were found to ranged from 1645.65 to 1935.45. Over all, the detailed evaluation of their fragmentation pathways, diagnostic ions, and their relative abundances enabled the identification of characteristic spectral features and facilitated the differentiation of structurally related isomeric compounds. This data set provide valuable analytical information for the verification of carbamates in environmental and related matrices, as well as during OPCW proficiency test (PTs).\n                  <\/jats:p>","DOI":"10.1002\/jms.70114","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T13:05:05Z","timestamp":1790082305000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mass Spectral Investigation of Carbamates Using EI and CI Techniques"],"prefix":"10.1002","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0725-5776","authenticated-orcid":false,"given":"Sandhya","family":"Bobbali","sequence":"first","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Department of Fluoro\u2010Agrochemicals CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Academy of Scientific and Innovative Research (AcSIR)  Ghaziabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramunaidu","family":"Addipilli","sequence":"additional","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Academy of Scientific and Innovative Research (AcSIR)  Ghaziabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Surya Vamsi","family":"Undrajavarapu","sequence":"additional","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6000-5490","authenticated-orcid":false,"given":"Bhanu Prasad","family":"Palivela","sequence":"additional","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Academy of Scientific and Innovative Research (AcSIR)  Ghaziabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Swarajya Lakshmi Vattem","family":"Venkata","sequence":"additional","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4270-9651","authenticated-orcid":false,"given":"Srinivas","family":"Kantevari","sequence":"additional","affiliation":[{"name":"Department of Fluoro\u2010Agrochemicals CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Academy of Scientific and Innovative Research (AcSIR)  Ghaziabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2573-162X","authenticated-orcid":false,"given":"Jagadeshwar Reddy","family":"Thota","sequence":"additional","affiliation":[{"name":"Centre for Mass Spectrometry, Department of Analytical and Structural Chemistry CSIR\u2010Indian Institute of Chemical Technology  Hyderabad India"},{"name":"Academy of Scientific and Innovative Research (AcSIR)  Ghaziabad India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12982-024-00161-6"},{"key":"e_1_2_8_3_1","first-page":"39","article-title":"Weapons of Mass Destruction: A Review of Its Use in History to Perpetrate Chemical Offenses","volume":"9","author":"Iannotti A.","year":"2016","journal-title":"Defence S&T Technical Bulletin"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-819090-6.00003-9"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/9781788010092-00025"},{"key":"e_1_2_8_6_1","article-title":"The OPCW: Model or Anomaly","volume":"14","author":"Tabassi L.
