Chromatographic and Mass Spectral Studies on Mass Equivalent Substituted Phenethlamines Related to MDEA, MDMMA and MBDB 

Thigpen, Ashley (2006-12-15)
The goal of this project is to evaluate the GC-MS properties of a series of twelve regioisomeric and isobaric ring substituted phenethylamines with identical molecular weight and major fragmentation ions. Three regioisomeric ...

GC-MS and GC-IRD Studies on Ethoxyphenethylamines Related to MDEA, MDMMA and MDBD 

Al-Hossaini, Abdullah (2009-12-17)
Three regioisomeric 3,4-methylenedioxyphenethylamines having the same molecular weight and major mass spectral fragments of equal mass have been reported as drugs of abuse in recent years. These compounds are 3,4-methyle ...

GC-MS Studies on a Series of 1-pentylacylindoles: Regioisomeric Compounds Related to the Synthetic Cannabinoids. 

Alsegiani, Amsha (2016-07-12)
This thesis is primarily focused on analytical approaches to differentiate twenty isomeric compounds related to designer drugs of the1-pentyl-acylindoles class. The compounds investigated represent a series of synthetic ...

Mass Spectral and Chromatographic Studies on a Series Of Regioisomers and Isobaric Derivatives Related to Methylenedioxymethamphetamines 

Awad, Tamer (2006-12-15)
The popular drug of abuse 3,4-methylenedioxymethamphetamine (MDMA) has regioisomeric and isobaric substances of mass equivalence, which have similar analytical properties and thus the potential for misidentification. Direct ...

Mass Spectral, Infrared and Chromatographic Studies on Designer Drugs of the Piperazine Class 

Hafiz Abdel-Hay, Karim (2012-02-20)
The controlled drug 3,4-methylenedioxybenzylpiperazine (3,4-MDBP) has regioisomeric and isobaric substances of mass equivalence, which have similar analytical properties and thus the potential for misidentification. The ...

Synthesis, Analytical Profiles and Receptor Pharmacology of Methoxylated Derivatives and Regioisomers of the NBOMe series of Hallucinogenic Drugs 

Almalki, Ahmad (2019-04-23)
The potential for designer analogue development in the NBOMe series of drugs of abuse is very high based on the methods used to synthesize this class of compounds, and the availability of a wide variety of precursor ...

Synthesis, GC–MS, GC–MS/MS, GC–IR and chromatographic studies on cathinone derivatives related to methylenedioxypyrovalerone (MDPV) 

Abiedalla, Younis (2018-12-03)
This project will address issues of resolution and discriminatory capabilities for cathinone derivatives (regioisomeric and homologous groups) providing additional reliability and selectivity for forensic evidence and ...
